Phototransamidation as a method for the synthesis of N-glycosyl asparagines

Vizvardi, Kristof,Kreutz, Christian,Davis, Alexander S.,Lee, Vincent P.,Philmus, Benjamin J.,Simo, Ondrej,Michael, Katja

, p. 348 - 349 (2003)

N-Glycosyl asparagines were synthesized by a mild photochemical coupling method in which a photoreactive amide of an aspartic acid's β-carboxyl group is condensed with an aminosaccharide. Upon excitation, the γ-carbon becomes susceptible to nucleophilic a
