A cross-coupling reaction between N-sulfonyl aziridines and organozinc reagents is possible under mild and functional-group-tolerant conditions in the presence of inexpensive and air-stable Ni(II) source and dimethyl fumarate as ligand to yield β-substituted amines. The stereoselectivity of the reaction is consistent with a stereoconvergent mechanism wherein the sulfonamide directs C-C bond formation.
