Several substituted 1-β-D-ribofuranosyl-1,2-dihydro-2-oxopyridines have been prepared as congeners of nicotinamideribonucleoside. Direct glycosylation of the silylated 3-ethylcarboxylate 5 or 3-carbamoyl 6 derivative of 1,2-dihydro-2-oxopyridine with 1,2,3,5-tetra-O-acetyl-β-D-ribofuranose (7) in the presence of trimethylsilyl triflate gave the corresponding blocked nucleosides 8 and 9, respectively
