摘要:
the asymmetric synthesis of(S)-malic esters was carried out by reduction of beta-ketosulfoxides derived from beta-ketoesters as well as the transformation of(S)-malic esters into syn and anti-1,2-diols via the reduction of beta-keto-gamma-alkoxy-sulfoxides. An application to the preparation of 2-deoxy-D-ribose and 2-deoxy-L-xylose derivatives is described.
