A copper-catalyzed oxyalkylation of allylic alcohols using nonactivated alkyl nitriles as reaction partners was developed. A sequence involving generation of an alkyl nitrile radical followed by its addition to a double bond and a copper-mediated formation of C(sp3)-O bond was proposed to account for the reaction outcome. The protocol provided an efficient route to functionalized tri- and tetrasubstituted epoxides via formation of a C(sp3)-C(sp3) and a C(sp3)-O bond with moderate to excellent diastereoselectivity.

A copper-catalyzed alkylation of allylic alcohols by alkyl nitriles with concomitant 1,2-aryl migration was developed. Formation of the alkyl nitrile radical was followed by its intermolecular addition to alkenes and the migration of a vicinal aryl group with the concomitant generation of a carbonyl functionality to complete the domino sequence. Mechanistic studies suggested that 1,2-aryl migration proceeded through a radical pathway (neophyl rearrangement). The protocol provided an efficient route to functionalized ketones containing an α-quaternary center.
