In this work we have studied the monoreduction of different 1,2-diaryl-ethanediones (benzils, 1) with lyophilised whole cells from Pichia glucozyma CBS 5766, using the diphenyl compound (benzil, 1a) as model substrate, and extended the enantioselective reduction to structurally different symmetric benzils for producing enantiomerically pure or enriched benzoins (α-hydroxyketones 2) in high yields and
