bond formation reactions have been made in recent years through the use of transition-metal-catalyzed cross-coupling reactions of racemic secondary alkyl electrophiles with organometallic reagents. Herein, we report a general process for the asymmetric construction of alkyl-alkyl bonds adjacent to heteroatoms, namely, a nickel-catalyzed enantioconvergent reductive hydroalkylation of olefins with α-heteroatom
近年来,通过使用外消旋仲烷基亲电试剂与有机金属试剂的过渡金属催化交叉偶联反应,对映收敛 C(sp3)-C(sp3) 键形成反应取得了重大进展。在此,我们报告了与杂原子相邻的烷基-烷基键的不对称构建的一般过程,即镍催化的烯烃与 α-杂原子磷或硫烷基亲电试剂的对映聚合还原加氢烷基化反应。包括使用容易获得的烯烃,该反应具有相当大的优势,如反应条件温和、底物范围广、官能团兼容性好,使其成为传统亲电-亲核交叉偶联反应的理想替代方案。
