STEREOCHEMICAL STUDIES - LVIII. SYNTHESIS OF OPTICALLY ACTIVE COMPOUNDS BY THE NOVEL USE OF MESO-COMPOUND-2. EFFICIENT SYNTHESIS OF AN OPTICALLY PURE STEROID INTERMEDIATE.

In order to explore the general application of a novel method for preparing optically active compounds, synthesis of the optically pure steroid intermediate ((-)-1) has been examined by employing the diol (2) as a meso-compound and N-mesyl-(S)-phenylalany
