  Optical Resolution of 3-(Silyloxy)glutaric Acid Half Esters and Their Utilization for Enantioconvergent Synthesis of a HMG-CoA Reductase Inhibitor

  摘要：

  Useful chiral synthons, (3R)- and (3S)-[(tert-butyldimethylsilyl)oxy]penta acid monomethyl ester, (R)-1 and (S)-1, were obtained by optical resolution of a racemic mixture of 1. Sulfoxide 8 has been developed from(S)-1 as a new building block for preparing HMG-CoA reductase inhibitors. Two alternate chiral synthons 2 and 8, synthesized from (R)-1 and(S)-1, respectively, were employed for enantioconvergent synthesis of potent inhibitor 15 containing a pyrrole moiety.
