Herein, we present a facile and efficient allylation method via Ni-catalyzed cross-electrophile coupling of readily available allylic acetates with a variety of substituted alkenyl bromides using zinc as the terminal reductant. This Ni-catalyzed modular approach displays excellent functional group tolerance and a broad substrate scope, which the creation of a series of 1,4-dienes including several
在此,我们提出了一种简便有效的烯丙基化方法,该方法通过镍催化的易得的烯丙基乙酸酯与各种取代的烯基溴化物的交叉亲电偶联,使用锌作为末端还原剂。这种镍催化的模块化方法显示出优异的官能团耐受性和广泛的底物范围,可产生一系列 1,4-二烯,包括几种结构复杂的天然产物和药物基序。此外,偶联策略具有实现对映体控制的潜力。这种转化的实用性通过对天然抗肿瘤活性分子β-榄香烯的有效修饰得到证明。
