A photoredox-copper dual-catalyzed cross dehydrogenative coupling reaction of glycosides with benzylic C—H substrates has been developed. The reaction proceeds smoothly under mild reaction conditions and features the using of readily accessible starting materials, which allows the highly site-selective synthesis of diverse glycosides O-alkylation products in 27%~72% yields, providing a new synthetic tool for the site-selective modification of glycosides.

Key words: photoredox catalysis, copper catalysis, site-selective alkylation, glycosides
