The approach to brefeldin A described herein hinges on Ru(II)-catalyzed cycloisomerization of an enyne obtained by the reaction of an alkynylzinc reagent with an α-chloro sulfide. Other key steps include Mislow-Evans rearrangement, cross-metathesis, and macrocyclization using a Roush-Masamune protocol.
本文所述的布雷菲德菌素 A 的方法依赖于 Ru(II)-催化的烯炔的环异构化反应,该烯炔是由炔基锌试剂与α-氯代硫化物反应得到的。其他关键步骤包括 Mislow-Evans 重排、交叉复分解以及使用 Roush-Masamune 方案进行的大环化反应。
