A monoselective synthesis of aryl-C-Δ1,2-glycosides from 1-iodoglycals via palladium-catalyzed ortho-C–H activation of N-quinolyl benzamides has been developed. An amino acid derivative was used as a crucial ligand to improve the yield and monoselectivity of the coupling reaction. The utility of this protocol was demonstrated by a concise synthesis of key moieties of some natural products.

This study describes the nickel-catalyzed reductive decarboxylative/deaminative glycosylation of activated aliphatic acids/amines. Various alkyl C-glycosides were efficiently constructed under simple and mild reaction conditions. The reactions were high-yielding and exhibited a broad substrate scope, thereby enabling the transformation of some structurally complex natural products and late-stage modifications
