Baker's yeast catalysed enantioselective reduction of chroman-4-ones

Substituted chroman-4-ones 1a-10a on catalytic reduction with Baker's Yeast give (S)-chroman-4-ols 1c-11c with high enantioselectivity. The absolute configuration has been determined by specific rotation and CD spectra.

A NEW SYNTHETIC APPROACH TO THE ROTENOID RING SYSTEM

The (+)-cis-chromanochromanones (2) and (3), respresenting the basic ring system of the natural insecticide rotenone, have been synthesised by a general procedure; the key step is 4-aroylation of the 4-(phenyl-sulphonyl)chromans (7; Z=SO2Ph).
