Azidoheteroarylation of unactivated olefins through distal heteroaryl migration

The radical-mediated azidoheteroarylation of unactivated olefins has been accomplished for the first time based on the strategy of intramolecular distal heteroaryl migration. A variety of synthetically useful heteroaryl-substituted alkyl azides are readily furnished under mild reaction conditions. The utility of the protocol is manifested by readily converting the products to piperidine, β-pipecolic acid, and triazole derivatives.
