Some aspects of the chemistry of Reissert compounds / |nDurga Prasad Aysola. -- 260 St. Catharines [Ont. : s. n.],

1-(0- and m-Ohlorobenzoyl)isoquinolines have been synthesized by two routes involving Reissert compounds. One route involves condensation of 2-benzoyl-l,2-dihydroisoquinaldonitrile with the appropriate chlorobenzaldehyde and the second involves rearrangement of the appropriate Z-(chlorobenzoyl)-l,Z-dihydroisoquinaldonitrile under basic conditions. The action of potassamide in anhydrous liquid ammonia on both ketones gave unexpectedly N-(l-isoquinolyl)benzamide (67) as the major product and the use of dibenzo-18-crown-6-ether 98% substantially improved the yd..e.ld in the case of l-chloroketone. This amide (67) exhibits unusual hydrogen bonding. 1-(o-chlorobenzoyl)-6,7-dimethoxyisoquinoline (79) was prepared in very s,amll quantities by the route involving condensation of 2-benzoyll, Z-dihydro-6,7-dimethoxyisoquinaldonitrile with o-chlorobenzaldehyde. The poor yields are due to the instability of the anion of 2-benzoyl1, Z-dihydro-6,7-dimethoxyisoquinaldonitrile. Attempted preparation of the ketone (79) by rearrangement of 2-(o-chlorobenzoyl)-l,2-dihydro6,7- dimethoxyisoquinaldonitrile under basic conditions yielded the start~ng material (Reissert compound) and 6,7-dimethoxyisoquinoline. The action of potassamide in anhydrous liquid ammonia on l-(o-bromo-4,5-dimethoxybenzoyl)isoquinoline (85), which was prepared by the route involving the condensation of 2-benzoyl-l,4-dihydroisoquinaldonitrile with o-bromo-4,5-dimethoxybenzaldehyde, gave two products, which have not yet been identified. The ketone (85) and its precursors are interest~ng in that their 20 eV and 70 eV mass spectra do not show molecular ions.

The relationship between stem-form, stand-closure and site -conditions : the influence of environmental conditions on tree allometry and forest structure in west-central Alberta

Changes in the configuration of a tree stern result insignificant differences in its total volume and in the proportion of that volume that is merchantable timber. Tree allometry, as represented by stem-fo~, is the result of the vertical force of gravity and the horizontal force of wind. The effect of wind force is demonstrated in the relationship between stem-form, standclosure and site-conditions. An increase in wind force on the individual tree due to a decrease in stand density should produce a more tapered tree. The density of the stand is determined by the conditions that the trees are growing under. The ability of the tree to respond to increased wind force may also be a function of these conditions . This stem-form/stand-closure/site-conditions relationship was examined using a pre-existing database from westcentral Alberta. This database consisted of environmental, vegetation, soils and timber data covering a wide range of sites. There were 653 sample trees with 82 variables that formed the basis of the analysis. There were eight tree species consisting of Pinus contorta, Picea mariana, Picea engelmannii x glauca, Abies lasiocarpa, Larix laricina, Populus tremuloides, Betula papyrifera and Populus balsamifera plus a comprehensive all-species data set. As the actual conformation of the stern is very individual, stem-fo~was represented by the diameter at breast height to total height r~tio. The four stand-closure variables, crown closure, total basal area, total volume and total number of stems were reduced to total basal area and total number of stems utilizing a bivariate correlation matrix by species. Site-conditions were subdivided into macro, meso and micro variables and reduced in number 3 using cross-tabulations, bivariate correlation and principal components analysis as screening tools. The stem-fo~/stand-closure relationship was examined using bivariate correlation coefficients for stem-fo~ with total number of stems and stem-fo~ with total basal area. The stem-fo~/site-conditions and the stand-closure/site- conditions relationships were examined using multiple correlation coefficients. The stem-form/stand-closure/site-conditions relationship was examined using multiple correlation coefficients in separate analyses for both total number of stems and total basal area. An increase in stand-closure produced a decrease in stem-form for both total number of stems and total basal area for most species. There was a significant relationship between stem-form and site-conditions and between stand-closure and site-conditions for both total number of stems and total basal area for most species. There was a significant relationship between the stemform and site-conditions, including the stand-closure, for most species; total number of stems was involved independently of the site-conditions in the prediction of stem-form and total basal area was not. Larix laricina and Betula papyrifera were the exceptions to the trends observed with most species. The influence of both stand-closure (total number of stems in particular) and site-conditions (elevation in particular) suggest that forest management practices should include these- ecological parameters in determining appropriate restocking levels.

Military Appointment

George Ridout (1791-1871) was a member of the York volunteers during the War of 1812. He served as 3rd lieutenant in the grenadier company of the York militia, fought in the Battle of Queenston Heights, and was taken prisoner of war in April, 1813 when the Americans occupied York. Ridout studied law, and was admitted to the bar in Janurary 1813. He was an active member of the Law Society of Upper Canada, becoming a bencher in 1820, serving as treasurer for several years, and assisting in the development of the library. In 1828 he was appointed judge of the Niagara District Court and reappointed in 1832. In 1836, Sir Francis Bond Head, Lieutenant-Governor, charged Ridout with insult to the person and office of the Lieutenant Governor and disloyalty to the policies of the crown, and dismissed him from his offices. Ridout denied the charges and was eventually ordered to be reinstated by Lord Glenelg, the colonial secretary. Sir Francis Bond Head refused to do so, and instead chose to resign.

Brown Bess Musket

This original Brown Bess musket is an East India Pattern musket (3rd model) as it has a 39 inch barrel, a brass side plate on the opposite side of the lock and has no tail to it. The tang on the butt plate is also short. The lock mechanism reveals that this musket has been converted to a percussion cap musket, which became popular in the 1820s. It was assembled at the Tower of London and is engraved with a crown, "GR" and an "X", on the top of the barrel. There is also a ".W. Reg.t" marking on the side of the barrel. This rare musket is typical of the muskets carried by British and Canadian soldiers during the War of 1812 and the Rebellion of 1837.

St. Lawrence Seaway Authority fonds, 1984-1991, n.d.

The St. Lawrence Seaway is a system of locks, canals and channels. Construction of the seaway began in 1954 and it opened on April 25th, 1959. It consists of a 189 mile (306 kilometer) stretch of the seaway between Montreal and Lake Ontario. The Seaway is considered to be an engineering feat with 7 locks in the Montreal – Lake Ontario section which lift vessels to 246 feet (75 meters) above sea level. The 28 mile (44 kilometer) Welland Canal is the fourth version of a link between Lake Ontario and Lake Erie. Today there are 8 Canadian locks which lift ships 326 feet (100 meters) over the Niagara Escarpment. The St. Lawrence Seaway Authority is a Canadian Government Crown Corporation which is financially self-sufficient. It depends on the tolls charged to the users of the Seaway for its revenue and operating expenses.

Battlefield House flyer, n.d.

Battlefield House was originally the home of Mary Gage, a widow who arrived in Canada with 2 children after her husband was killed in action in the American Revolution in 1777. The original house was a log cabin which was replaced by a storey and a half frame house. Col. Nelson was the next owner of the house, and in the middle of the 19th century he raised the roof to make it a 2 storey house and added a large west wing. Successive owners: the Glover, Williams and Fisher families made a few changes to the house. The last owner was D.A. Fletcher who tore down the newer, western half of the building in 1895. In 1899, Mrs. John Calder, a granddaughter of James Gage formed the Women’s Wentworth Historical Society and raised enough money to buy the Gage Farmhouse and the land around it on which the Battle of Stoney Creek was fought. In 1910 this group purchased another 13 acres of the original Crown Grant and made 17 ½ acres of parkland open to the public. The women of the Society renovated and furnished the house. They maintained the building for 63 years. It was due to them that a monument was erected above the house by the Dominion Government. The monument was unveiled on the 100th anniversary of the Battle, June 6, 1913. The house was turned over by the Historical Society to The Niagara Parks Commission on January 19th, 1962.

Niagara Falls Park: Notice to Treat to Sutherland Macklem, Esquire, 1885

The Niagara Parks Commission administrative headquarters are located in Oak Hall which is on the cliff above Dufferin Islands. In 1798 this land was granted by the crown to United Empire Loyalist James Skinner until 1898. A century later it was the home of the Clarks, Streets and Macklems. These families controlled the mills of Bridgewater which was a pioneer industrial village located at Dufferin Islands. Then, it was known as Clark Hill. Colonel Thomas Clark, commander of the Second Lincoln Militia in the War of 1812 is the earliest known occupant of the house. When Clark died in 1837, the house went to Thomas Clark Street who was the son of the Colonel’s partner. Mr. Street was a bachelor and his sister, widow of Dr. T.C. Macklem, managed his household. Mrs. Macklem had 2 sons. The eldest son drowned in the Niagara River at the age of 8 and the younger son, Sutherland became heir to the estate. Mr. Macklem opened Cynthia Islands and Cedar Island to the public and had roads built to reach them. Two suspension bridges connected them to the mainland and tolls were charged on the bridges. The improvements to the land cost Macklem $18,962. He called the bridges “Bridge Castor” and “Bridge Pollux”. There was also an office built at the end of Bridge Castor. Macklem also spent $454 fixing up the Burning Spring Building (the burning spring is enclosed in a barrel which collects gas and lets it out through a tube at the top). Macklem received a yearly income of $56,378.79 from tourists and visitors. In 1887 Cynthia Islands and Cedar Island were deeded to the crown and became part of Queen Victoria Park. The name Cynthia was changed to Dufferin in honour of Lord Dufferin. Sources: www.niagarafrontier.com/parks.html www.niagarafrontier.com/burningsprings.html

(A) BODIPY as a versatile fluorophore (B) Synthesis of PNAs via Staudinger reaction

(A) In recent years, 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) fluorophores have attracted considerable interest due to their unique photochemical properties. However detailed studies on the stability of BODIPY and analogues under acidic and basic conditions have been lacking. Thus the stability of a series of BODIPY analogues in acidic (di- and trichloroacetic acid) and basic (aqueous ammonium hydroxide) conditions was investigated using 11B NMR spectroscopy. Among the analogues tested, 4,4-diphenyl BODIPY was the most stable under the conditions used in the experiments. It was found that reaction of 4,4-dimethoxy BODIPY with dichloroacetic acid gave mixed anhydride 4,4-bis(dichloroacetoxy) BODIPY in good yields. Treatment of the latter mixed anhydride with alcohols such as methanol and ethanol in the presence of a base afforded corresponding borate esters, whereas treatment with 1,2-diols such as ethylene glycol and catechol in the presence of a base gave corresponding cyclic borate esters. Furthermore treatment of 4,4-difluoro-8-methyl-BODIPY with secondary amines in dihalomethane resulted in carbon–carbon bond formation at the meso-methyl position of BODIPY via Mannich-type reactions. The resulting modified BODIPY fluorophores possess high fluorescent quantum yields. Five BODIPY analogues bearing potential ion-binding moieties were synthesized via this Mannich-type reaction. Among these, the BODIPY bearing an aza-18-crown-5 tether was found to be selective towards copper (II) ion, resulting in a large blue shift in absorption and sharp fluorescent quenching, whereas aza-15-crown-4 analogue was selected towards fluoride ion, leading to effective florescent quenching and blue shift. (B) Peptide nucleic acids (PNA), as mimics of natural nucleic acids, have been widely applied in molecular biology and biotechnology. Currently, the preparation of PNA oligomers is commonly achieved by a coupling reaction between carboxyl and amino groups in the presence of an activator. In this thesis attempts were made towards the synthesis of PNA through the Staudinger ligation reactions between C-terminal diphenylphosphinomethanethiol thioesters and N-terminal α-azido PNA building blocks.
