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

general features that result in enhanced binding to the sodiumchannel. These include a preferred 5-phenyl ring orientation and a favorable steric effect resulting from the C5-alkyl chain. This model was then utilized to accurately predict literature sodiumchannelactivities for hydantoins 14-20, which were not included in the training set. Finally the hydantoin CoMFA model was used to design the structurally
