An Fe(III)/NaBH(4)-mediated reaction for the functionalization of unactivated alkenes is described defining the alkene substrate scope, establishing the exclusive Markovnikov addition, exploring a range of free radical traps, examining the Fe(III) salt and initiating hydride source, introducing H(2)O-cosolvent mixtures, and exploring catalytic variants. Its use led to the preparation of a novel, potent, and previously inaccessible C20'-vinblastine analogue.
描述了一种 Fe(III)/NaBH(4)介导的用于活化烯烃功能化的反应,确定了烯烃底物的范围,建立了烯烃的 Markovnikov 加成,探索了一系列自由基捕获剂,考察了 Fe(III)盐和引发氢化物源,引入了 H(2)O-共溶剂混合物,并探索了催化变体。该方法的应用导致了一种新型、有效且以前无法获得的 C20'-长春碱类似物的制备。
