was enabled by an unprecedented 1,2-boryl carbon-to-nitrogen migration. Based on the discovery of a rearrangement of an α-borylalkylamido copper intermediate to an α-borylaminoalkyl copper species through 1,2-migration of a boryl group from carbon to nitrogen and copper migration from nitrogen to carbon, we have developed a copper-catalyzed selective allylation of a wide range of aldimines and ketimines
我们报告了催化亚胺催化的一般策略,这是由前所未有的1,2-硼基碳到氮的迁移实现的。基于通过硼基从碳到氮的1,2-迁移以及铜从氮到碳的迁移将α-硼烷基烷基酰胺基铜中间体重排为α-硼烷基氨基烷基铜物种的发现,我们开发了一种铜催化的在存在B 2(pin)2和LiO t Bu的情况下,将多种醛胺和酮亚胺与烯丙基亲电试剂选择性烯丙基化。我们期望这种催化的亚胺-苯丙氨酸催化策略可能会衍生出用于合成各种功能化胺的有用方法。
