Stereoselective alkylC-glycosylation of glycosyl estersviaanomeric C–O bond homolysis: efficient access toC-glycosyl amino acids andC-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.
