Letter to S.D. Woodruff regarding a resolution passed that the engineer be requested to examine the fence built by the contractors alongside of the Henry Vandenburgh Farm and report to the secretary as to whether this is a lawful fence, completed according to Williams’ contract. This is signed by Duncan McFarland, president. There is a reply written by S.D. Woodruff at the bottom of the letter stating that the fence is not built in accordance with the contract, Dec. 18, 1856.

A 2 ½ page letter addressed to The Editor of the Presbyterian Magazine, care of [illegible], London, C.W. The writer describes the Village of Chippawa and its location in Ontario. He writes that there are many people there of Scotch [Scottish] descent. He says that a congregation was formed and 39 names were on the roll. The letter is from J.P. [John Porteous] with an added note from Wm. Porteous. The letter is from St. Catharines. There is one postmark – St. Catharines, April 6, 1823 A 1 ½ page letter addressed to Rev. W. Proudfoot, Ed. Of Presbyterian Mag., London, C.W. This letter is from Walter Mitchell in St. Catharines. He sends a list of peoples’ names and the amounts that they have paid toward the Presbyterian Magazine. Mr. Mitchell is acting as an agent for the magazine. This letter has 1 postmark – St. Catharines, Sept. 13, 1842 A 2 page letter addressed to Rev. W. Proudfoot, London, C.W. This letter is from John Jennings of St. Catharines. The writer claims that he is ill but he makes plans to meet Reverend Proudfoot in Toronto in order to go to a meeting in Rochester. The writer expects that Reverend Proudfoot will preach in Rochester. The letter has 1 postmark – St. Catharines, Aug. 14, 1843. A 2 page letter addressed to The Rev. Professor Proudfoot, London, C.W. from John Porteaus of St. Catharines. The writer says that he will not preach in Detroit.

The exact mechanistic understanding of various organocatalytic systems in asymmetric reactions such as Henry and aza-Henry transformations is important for developing and designing new synthetic organocatalysts. The focus of this dissertation will be on the use of density functional theory (DFT) for studying the asymmetric aza-Henry reaction. The first part of the thesis is a detailed mechanistic investigation of a poorly understood chiral bis(amidine) (BAM) Brønsted acid catalyzed aza-Henry reaction between nitromethane and N-Boc phenylaldimine. The catalyst, in addition to acting as a Brønsted base, serves to simultaneously activate both the electrophile and the nucleophile through dual H-bonding during C-C bond formation and is thus essential for both reaction rate and selectivity. Analysis of the H-bonding interactions revealed that there was a strong preference for the formation of a homonuclear positive charge-assisted H-bond, which in turn governed the relative orientation of substrate binding. Attracted by this well-defined mechanistic investigation, the other important aspect of my PhD research addressed a detailed theoretical analysis accounting for the observed selectivity in diastereoselective versions of this reaction. A detailed inspection of the stereodetermining C-C bond forming transition states for monoalkylated nitronate addition to a range of electronically different aldimines, revealed that the origins of stereoselectivity were controlled by a delicate balance of different factors such as steric, orbital interactions, and the extent of distortion in the catalyst and substrates. The structural analysis of different substituted transition states established an interesting dependency on matching the shape and size of the catalyst (host molecule) and substrates (guest molecules) upon binding, both being key factors governing selectivity, in essence, offering an analogy to positive cooperative binding effect of catalytic enzymes and substrates in Nature. In addition, both intra-molecular (intra-host) and inter-molecular (host-guest, guest-guest) stabilizing interactions play a key role to the high π-facial selectivity. The application of dispersion-corrected functionals (i.e., ωB97X-D and B3LYP-D3) was essential for accurately modeling these stabilizing interactions, indicating the importance of dispersion effects in enantioselectivity. As a brief prelude to more extensive future studies, the influence of a triflate counterion on both reactivity and selectivity in this reaction was also addressed.
