A highly enantioselective copper/N-heterocyclic carbene catalyzed allylic arylation with organolithium compounds is presented. The use of commercial or readily prepared aryllithium reagents in the reaction with allyl bromides affords a variety of chiral diarylvinylmethanes, comprising a privileged structural motif in pharmaceuticals, in high yields with good to excellent regio- and enantioselectivities
提出了高度对映选择性的铜/ N-杂环卡宾与有机锂化合物的烯丙基芳基化反应。在与烯丙基溴的反应中使用市售或易于制备的芳基锂试剂可提供高收率的多种手性二芳基乙烯基甲烷,其在药物中具有优先的结构基序,具有良好或优异的区域和对映选择性。市售药物托特罗定(Detrol)的正式合成中说明了这种新转变的多功能性。
