A nickel‐catalyzed asymmetric reductive hydroarylation of vinyl amides to produce enantioenriched α‐arylbenzamides is reported. The use of a chiral bisimidazoline (BIm) ligand, in combination with diethoxymethylsilane and aryl halides, enables the regioselective introduction of aryl groups to the internal position of the olefin, forging a new stereogenic center α to the N atom. The use of neutral reagents
据报道,镍催化乙烯基酰胺的不对称还原氢化芳基化反应产生对映体富集的α-芳基苯甲酰胺。手性双咪唑啉(BIm)配体与二乙氧基甲基硅烷和芳基卤化物结合使用,可以将芳基区域选择性地引入烯烃的内部位置,从而将新的立体中心α锻造到N原子上。使用中性试剂和温和的反应条件可轻松获得抗癌药,SARS-CoV PLpro抑制剂和KCNQ通道开放剂中存在的与药理相关的基序。
