• A new short synthesis of coumestrol and its application for the synthesis of [6,6a,11a-13C3]coumestrol

  日期：2004.2

  A convenient and simple two-step method for the synthesis of coumestrol has been established, which involves a base catalysed condensation of phenyl acetate with benzoyl chloride, followed by demethylation and subsequent tandem intramolecular cyclisation. This method was then employed for the efficient synthesis of multiply 13C-labelled coumestrol.

  已经建立了方便和简单的两步合成香豆酚的方法，该方法涉及乙酸苯酯与苯甲酰氯的碱催化缩合，然后进行脱甲基化和随后的串联分子内环化。然后将该方法用于有效合成13 C-标记的香豆甾醇。
