characterised by possessing, in the central portion: (1) preferably, a dihydroxyethylene function, which is isosteric with a peptidic bond; (2) a peptidemimetic bridge between the two nitrogens of the main chain and (3) radicals capable of mimetising amino acids. These new protease inhibitors are a base for the preparation of anti-viral formulations capable of inhibiting HIV virus proliferation.

Disclosed herein are a process for producing an optically active ester by reaction of a racemic alcohol with an optically active amino acid derivative or optically active tartaric acid derivative, a process for producing an optically active alcohol by hydrolysis of said optically active ester, a process for converting an alcohol into a ketone by oxidation, a method for stably storing an optically active ketone, and a new optically active amino acid ester and a new optically active tartaric acid ester. These compounds are important as intermediates for medicines and agricultural chemicals.
