Abstract
Reduction of ethyl 4-t-butoxy-3-oxobutanoate with fermenting yeast yields (R)-ethyl 4-t-butoxy-3-hydroxybutanoate in 97% e.e. Since the protective group is readily removed from the product of reduction, the present procedure provides a simple entry to the "world of chiral blocks" formally derived from (R)-malic acid.
