We report herein an asymmetric Ni-catalyzed cross-electrophile coupling approach to prepare enantioenriched aryl/vinylalkyl carbinol esters through arylation/vinylation of easily accessible racemic 1-chloro-1-alkanol esters with aryl/vinyl electrophiles. The method features a broad substrate scope as demonstrated by more than 60 examples including the challenging chiral allylic esters. It tolerates
我们在此报告了一种不对称 Ni 催化的交叉亲电试剂偶联方法,通过芳基/乙烯基亲电试剂对易于获得的外消旋 1-氯-1-烷醇酯进行芳基化/乙烯基化来制备对映富集的芳基/乙烯基烷基甲醇酯。该方法具有广泛的底物范围,包括具有挑战性的手性烯丙基酯在内的 60 多个示例证明了这一点。它可以耐受多种官能团,包括烯基、羰基和游离羟基,这些官能团在传统的羰基还原和加成方法中可能无法存活。通过轻松制备一些关键中间体以及对手性药物和天然存在的化合物进行修饰,展示了本工作的合成效用。最后,我们描述了这种方法的有效一锅法。
