A highly stereoselective construction of the eight contiguous chiral centers of ansa-chains of rifamycins has been accomplished by the iterative use of the stereospecific methylation of γ,δ-epoxy acrylates by trimethylaluminum which was recently developed by us. The present work demonstrates the synthetic potential of the method for the synthesis of polypropionate antibiotics including ansamycins and
通过我们最近开发的三甲基铝对γ,δ-环氧丙烯酸酯的立体有择甲基化的迭代使用,已经实现了利福霉素ansa链的八个连续手性中心的高度立体选择性构建。本工作证明了该方法用于合成包括安沙霉素和大环内酯在内的聚丙烯酸酯抗生素的潜力。
