  Dimethyl amino[(phenylthio)methyl]malonate: a useful C-3 unit in a mild, direct synthesis of oxazole-4-carboxylates

  摘要：

  N-Acyl derivatives of the title compound undergo oxidative cyclization upon treatment with N-chlorosuccinimide in DMF to form dimethyl 4,5-dihydro(phenylthio)oxazole-4,4-dicarboxylates 4 which then are decarbomethoxylated with concomitant loss of thiophenoxide to form 2-substituted-4-carbomethoxy-5-unsubstituted oxazoles 1. The mildness and generality of this method has been demonstrated by the synthesis of a variety of examples, including a fragment used for a synthesis of calyculin A.

  日期：——

  Three advanced intermediates corresponding to the carbon skeleton of the hennoxazoles have been prepared. Central to the strategy is the synthesis of the oxazoles prior to coupling with the other fragments and a dithiane addition to allow for the generation of diastereomers of the natural product.

  已经合成了三个与氮杂环的碳骨架相应的高级中间体。该策略的核心是在与其他片段偶联之前合成氧杂环，并进行二硫杂烷的加成，以产生天然产物的非对映体。
