alkylation of aldehydes represents a straightforward strategy for the synthesis of chiral secondary alcohols. However, efficient methods using organoborons as coupling reagents are rare. Herein, we report a highly enantioselective nickel-catalyzed alkylation reaction of aldehydes, using readily available alkylborons as nucleophiles. A wide variety of chiral secondary alcohols were prepared from commercially
过渡金属催化的醛的不对称烷基化代表了合成手性仲醇的直接策略。然而,使用有机硼作为偶联剂的有效方法很少。在此,我们报道了一种高度对映选择性的镍催化的醛烷基化反应,使用容易获得的烷基硼作为亲核试剂。由市售醛以高产率制备了多种手性仲醇。优异的对映选择性和化学选择性的关键是使用大体积的C 2对称手性NHC配体。该方案具有优异的对映体控制性、条件温和、官能团相容性好等特点。
