An intermolecular syn-1,2-arylamination of unactivated alkenes with arylboronic acids and O-benzoylhydroxylamine electrophiles has been developed with Ni(II) catalyst. The cleavable bidentate picolinamide directing group facilitated formation of stabilized 4-, 5- or 6-membered nickelacycles and enabled the difunctionalization of diverse alkenyl amines with high levels of regio-, chemo- and diastereocontrol. This general and practical protocol was compatible with broad substrate scope and high functional group tolerance. The utility of this method was further demonstrated by the site-selective late-stage modification of pharmaceutical agents.
