dichloroketene to a chiral enol ether, followed by Beckmann ring expansion and dechlorination, affords a potential intermediate for the synthesis of various natural products. The usefulness of this intermediate is first demonstrated by an asymmetric synthesis of (-)-detoxinine.
已知内酰胺的烯丙基氧化,通过二氯乙烯酮与手性烯醇醚的不对称 [2+2] 环加成反应,然后进行贝克曼扩环和脱氯反应,为合成各种天然产物提供了一种潜在的中间体。这种中间体的有用性首先通过 (-)-detoxinine 的不对称合成得到证明。
