is described. A unique, Rh-catalyzed amination reaction provides rapid access to the heteratom-rich, tricyclic core of the toxin, which is common to more than 30 related natural products. The completed route should facilitate the preparation of other naturally occurring PSPs and designed analogues thereof.
描述了麻痹性贝类毒物 (P
SP)、(+)-gonyautoxin 3 的不对称合成。独特的 Rh 催化胺化反应可快速获取毒素的富含杂原子的
三环核心,这在 30 多种相关
天然产物中很常见。完成的路线应有助于其他天然存在的 P
SP 及其设计的类似物的制备。
