Stereoselective alkyl C -glycosylation of glycosyl esters via anomeric C–O bond homolysis: efficient access to C -glycosyl amino acids and C -glycosyl peptides

A novel photoredox-catalyzed radical conjugate addition of 1,4-dihydropyridine-derived glycosyl esters and dehydroalanine derivatives via anomeric C(sp 3 )–O bond homolysis to construct C -glycosyl amino acids and peptides is for the first time described.
