Quaternary geology of the Campbellford, Trenton, Consecon, Tweed, Belleville, Wellington, Sydenham, Bath, and Yorkshire Island map-areas, Ontario /

Sediment relationships observed during geological mapping in southeastern Ontario indicate a relatively simple deglaciation history for the area during late Wisconsin time. The ice from the north (part of the Lake Simcoe lobe) and the Lake Ontario ice lobe, which were coalesced during most of late Wisconsin time, initially separated along the crest of the Oak Ridges Moraine. Available data indicate that the Oak Ridges Moraine is composed primarily of sediments pre-late Wisconsin in age capped by late Wisconsin till and interlobate deposits. Retreat of the northern ice was relatively steady and resulted in the deposition of the Dummer Moraines, a facies of the drumlinized till to the south. Retreat of the Lake Ontario ice lobe into the Lake Ontario basin was interrupted by a re-advance which covered the southeastern half of the map area. The northern ice had already retreated from the area by this time. The Lake Ontario lobe was fed through the St. Lawrence Valley, indicating that the Ottawa Valley was ice filled at this time. High level glacial lakes fronted the ice during deglaciation. These waters quickly fell to low levels as the ice retreated from the St. Lawrence Valley, opening lower outlets.

An investigation into fungal metabolism of halogenated and related steroids

Fungal metabolism of halogenated and related steroids was investigated. The fungi Aspergillus niger ATCC 9142, Curvularia lunata NRRL 2380 and Rhizopus stolonifer ATCC6227b were studied in this regard. 2l-Fluoro-, 2l-chloro, 2l-bromo- and 2l-methyl-pregn-4-ene-3,20diones were prepared and incubated with ~ niger (a C-2l-hydroxylator) in order to observe the effect of the C-2l substituent on the metabolism of these substrates. In all four cases, the C-2l substituent prevented any significant metabolism of these substrates. llB-Fluoropregn-4-ene-3,20-dione was prepared and incubated with C. lunata (an llB-hydroxylator) and ~ stolonifer (an lla-hydroxylator). With ~ lunata, the ll-fluoro- substituent prevent hydroxylation at the 11 position, but diverted it to a site remote from the fluorine atom. In contrast, with ~ stolonifer the llB-fluoro- substituent, although slowing the apparent rate of hydroxylation, did not prevent its occurrence at the 11a- position. llB-Hydroxypregn-4-ene-3,20-dione was also incubated with R. stolonifer. The llB-hydroxy-;group did not appear to have any significant effect on hydroxylation at the lla- position. The incubation of a substrate, unsaturated at a favoured site of hydroxylation with Rhizopus arrhizus ATCC 11145 provided a complex mixture of products; among them were both the a and S epoxides. The formation of these products is rationalized as arising because of the lack of regio- and stereospecificity of the hydroxylase enzyme(s) involved.

Two enantiodivergent syntheses of balanol and the chemoenzymatic synthesis of oseltamivir

The present thesis outlines our latest findings on the reactivity of the Burgess reagent with oxiranes. Structural, mechanistic, and computational studies are presented. Included is the development of a (-)-menthyl version of the Burgess reagent and its application to the synthesis of enantiomerically pure ~-amino alcohols. This methodology has been exploited in the formal enantiodivergent synthesis of the (+)- and (-)-isomers of balanol. Also described is a second generation approach to both balanol enantiomers; each commencmg with the chemoenzymatic dihydroxylation of bromobenzene. This study also describes the steric and functional limitations of the toluene dioxygenase-mediated oxidation of benzoate esters. The metabolite derived from ethyl benzoate was employed in a formal synthesis of oseltamivir. Finally, several synthetic approaches to oseltamivir and its analogs are presented, each proceeding through a different vinyl aziridine derived from bromobenzene and ethyl benzoate.
