Part 1. Lewis Base-Catalyzed Cross-Aldol Reactions of Aldehydes: Preparative and Mechanistic Studies. Part 2. Initial Studies on Lewis Base-Catalyzed Reactions of Silyl Ynol Ethers With Aldehydes
… have been spectroscopically identified as chlorohydrins, and they can be trapped in situ with tert-butyl isocyanide to afford an alpha-hydroxy lactone and alpha-hydroxy amide in good overall yield. Last, proof of principle for Lewis base activation of acids in reactions of silyl ynol ethers …

1. Reinvestigation of a catalytic, enantioselective alkene dibromination and chlorohydroxylation, 2. Double cross-coupling reactions of siloxaborolates, 3. The enantioselective synthesis of 3-substituted morpholines using computer-guided catalyst design
In Chapter 1, attempts to reproduce eight, putative, enantioselective dibromination and chlorohydroxylation reactions from oft-cited literature studies are described. The reactions were performed with full fidelity to the original report wherever possible. Analysis of the enantiomeric composition …
