✦ Synopsis

Baker's yeast mediated reduction of the cc-acetoxy ketones (l)-( 2) proceeds with high enantio-and stereoselectivity to give the anti carbinols ($)-( 6), ea:ily converted into the masked chiral deoxy sugars ( 12)-( 14), --from which E-and k-deoxyzugars have been obtained.

Carbohydrates are now being used as starting materials in the synthesis of enantiomerically pure forms of natural products and drugs belonging to quite different structural 1 classes. In
