A series of α-amino ketones were reduced using asymmetric transfer hydrogenation (ATH) through a dynamic kinetic resolution (DKR). The protecting group was matched to the reducing agent, and following optimization, a series of substrates were investigated, giving products in high diastereoselectivity, over 99% ee in several cases and full conversion. The methodology was applied to the enantioselective synthesis of an MDM2-p53 inhibitor precursor.
Examining the origin of selectivity in the reaction of racemic alcohols with chiral N-phosphoryl oxazolidinones

A range of known and novel N-phosphoryl oxazolidinones and imidazolidinones were prepared and screened in the kinetic resolution of a range of racemic magnesium chloroalkoxides. Models are proposed to account for the enantioselectivity achieved based on a combination of chiral relay effects, generation of transient stereochemistry and the structure of the intermediate magnesium alkoxide.

Design and synthesis of metabolically stabilized inhibitors of TNF-α production, which could be new drug candidates, are reported. Conformational analysis of an active diastereoisomer was performed based on biological evaluations of the conformationally f
