radical from the O–H bond of cyanohydrin promoted by visible-light photoredox catalysis is reported. The alkoxy radical triggers the successive remote HAT and intramolecular cyano migration, leading to the regioselective cyanation of remoteC(sp3)–Hbonds. The reaction exhibits a broad functional group tolerance that allows many sensitive groups to remain intact under mild conditions. To demonstrate
