A nickel-catalyzedcross-coupling reaction between N-sulfonyl aziridines and organozinc reagents is reported. The catalytic system comprises an inexpensive and air-stable Ni(II) source and dimethyl fumarate as ligand. Regioselective synthesis of β-substituted amines is possible under mild and functional-group-tolerant conditions. The stereoselectivity of the reaction is consistent with a stereoconvergent
报道了 N-磺酰基氮丙啶和有机锌试剂之间的镍催化交叉偶联反应。该催化系统包含廉价且空气稳定的 Ni(II) 源和富马酸二甲酯作为配体。β-取代胺的区域选择性合成在温和和官能团耐受的条件下是可能的。该反应的立体选择性与其中磺酰胺指导 CC 键形成的立体会聚机制一致。
