Abstract
Biocatalytic asymmetric reductions have been key steps in the synthesis of 1,1-dimethoxy-2-propanone, catalyzed by suitable ketoreductases to (S)- and (R)-1,1-dimethoxy-2-propanol, obtained in ≥99.9% ee and excellent yield. Removal of the protecting group gave the (S)- and (R)-lactaldehydes in excellent yield and purity.
