The present invention has its objects to provide a method for reducing α-aminoketone derivatives under mild conditions with high stereoselectivity.
This invention is a method for reducing α-aminoketone which comprises reacting an α-aminoketone derivative of general formula (1) with a compound prepared from an organoaluminum compound of general formula (4), a sulfonic acid derivative of general formula (5), and an alcohol compound of general formula (6) to give an α-aminoalcohol derivative of general formula (7).

A series of HIV-1 proteinase inhibitors was synthesized based upon a single penicillin derived thiazolidine moiety. Reaction of the C-4 carboxyl group with (R)-phenylalaninol gave amide 10 which was a moderately potent inhibitor of HIV-1 proteinase (IC50 = 0.15 microM). Further modifications based on molecular modeling studies led to compound 48 which contained a stereochemically unique statine-based
