介绍了由Frateuria sp. W-315生产的一系列黄色多烯-多元醇抗生素——ENXs的合成研究。采用连续Wittig反应制备了C1′-C8′多烯片段。以(S)-异丙基甘油醛为原料,采用Yamaguchi的乙酰基环氧化物亲核取代反应和Marshall的烯基介导反应为关键步骤,构建了C9′-C15′和C10′-C15′片段。
Synthetic studies of enacyloxins (ENXs), a series of yellow-colored, polyene-polyol antibiotics produced by Frateuria sp. W-315, are described. The C1′-C8′ polyene fragments were prepared using successive Wittig reactions. The C9′-C15′ and C10′-C15′ fragments were constructed from (S)-isopropylideneglyceraldehyde using Yamaguchi's nucleophilic substitution reaction of acetylide to epoxide, and/or Marshall's allenylindium mediated reaction as the key steps.
