The first total synthesis of the potent antifungal and cytotoxic agent (+)-crocacin D in optically pure form following a convergent strategy is described here. The regioselective ring opening of a silyl-substituted epoxide with an azide ion, based on a method developed by us earlier, and subsequent subjection of the resulting α-azido-β-hydroxyalkylsilane intermediate to a Peterson elimination reaction
本文介绍了收敛策略后,光学纯净形式的有效抗真菌和细胞毒剂(+)-crocacin D的第一个全合成。根据我们之前开发的方法,使用叠氮化物离子对甲硅烷基取代的环氧化物进行区域选择性开环,然后在合成过程中的适当阶段对所得的α-叠氮基-β-羟烷基硅烷中间体进行Peterson消除反应构成了关键的分子顺式烯酰胺部分的立体选择性构建的关键步骤。
