A concise pathway to synthesize a novel class of pyrido(2,3-d)pyrimidine-C-β-d-glycosides
چکیده انگلیسی

A concise pathway to synthesize a novel class of nine different pyrido(2,3-d)pyrimidine-C-β-d-glycosides is reported. Formation of Michael adduct as an intermediate followed by heterocyclization are the key steps and the products were characterized by different spectral studies. β-Anomeric forms of C-glycosides were assigned from 1H NMR spectroscopy.
