Diastereoselectivity in the reduction of alpha-alkoxy-, alpha-acyloxy-, and alpha-alkylamino-substituted ketones with polymethylhydrosiloxane (PMHS) in the presence of fluoride ion catalysis was investigated. High syn-selectivity was observed in the reduction of alpha-alkoxy, alpha-acyloxy, and alpha-dialkylamino ketones. Reduction of alpha-monoalkylamino ketone proceeded in anti-selective manner with

A process for the synthesis of hydroxyethylene dipeptide isosteres from .alpha.-N,N-di(protected)-amino(alkyl or substituted alkyl)methyl ketones that can be efficiently carried out on an industrial scale. The process proceeds with excellent diastereoselectivity and chemical efficiency, and can be used to prepare a wide variety of hydroxyethylene dipeptide isosteres for a variety of uses, including as HIV-1 protease inhibitors and renin inhibitors.
