Regioselective reduction of the 5-keto group of tert-butyl 4-methyl-3,5-dioxohexanoate (1) leads to a stereodiad of tert-butyl5-hydroxy-4-methyl-3-oxohexanoate (2). Alcohol dehydrogenases from Lactobacillus brevis (LBADH), Rhodococcus sp. (RS 1-ADH) and Saccharomyces cerevisiae (YGL157w) reduce 1 under dynamickineticresolution conditions, thereby establishing two chiral carbons with a single reduction
