  Stereoselective Total Synthesis of (+)-Cardiobutanolide

  摘要：

  Stereoselective synthesis of styryllactone (+)-cardiobutanolide was accomplished in good overall yield from D-(-)-tartaric acid. Key features of the synthesis include the elaboration of a gamma-hydroxy butyramide obtained from the dimethylarnide of tartaric acid, involving a combination of the addition of 1,3-dithian-2-yllithium and stereoselective reduction.
