摘要

Reaction of allyl aryl sulfides and α-diazoacetic acid esters in the presence of optically active Co (III)-salen complex (8-Br) provided 3-substituted 2-arylthio-4-pentenoic acid esters stereoselectively by way of enantioselective S-ylide formation and subsequent diastereoselective [2, 3] sigmatropic rearrangement. For example, the reaction of cinnamyl phenyl sulfide and (−)-menthyl α-diazoacetate provided (−)-menthyl (2R, 3S)-2-phenylthio ...
