2-octanethione have been reduced with baker'syeast to give optically active thiols. The reductions parallel those of the oxygen analogues with respect to rate and diastereo- and enantioselectivity but, generally, the enantiomeric excess (ee) values are smaller. The influence of experimental variables such as substrate concentration, physiological condition of the yeast (resting/fermenting, fresh/dry/frozen)
