Several different types of reactions characteristic of organocuprates have been studied using reagents RTRRCu(CN)LiNa derived from CuCN and one equivalent each of an organolithium (RTLi) and organosodium (RRNa) species.
已经使用衍生自CuCN的试剂R T R R Cu(CN)LiNa以及有机锂(R T Li)和有机钠(R R Na)物种中的每一个当量来研究几种不同类型的有机铜酸盐特征反应。
Iridium-Catalyzed 1,3-Rearrangement of Allylic Ethers
The 1,3-rearrangement of allylic derivatives has rarely been reported, except for allylic alcohols. Herein, we describe an iridium-catalyzed 1,3-rearrangement of readily available allylic ethers to access the difficultly prepared allylic ethers with a large steric hindrance. The developed method shows a broad substrate scope and could be used in the late-stage modification of several natural products
