  Nucleosides. 141. Synthesis of 5-.beta.-D-ribofuranosylnicotinamide and its N-methyl derivative. The isosteric and isoelectronic analogs of nicotinamide nucleoside

  摘要：

  The pyridine C-nucleosides 5-beta-D-ribofuranosylnicotinamide and its N-methylpyridinium derivative (1 and 2), which are isosteric and isoelectronic, respectively, to nicotinamide nucleoside were synthesized. Condensation of 3-bromo-5-lithiopyridine with 2,4:3,5-di-O-benzylidene-D-aldehydoribose (7) afforded an allo/altro mixture of the corresponding bromopyridine derivatives, which were converted into nicotinamide C-nucleoside precursors 10. Mesylation of the hydroxyl group of 10 followed by acid hydrolysis of the product afforded the anomeric nicotinamide C-nucleosides. The beta anomer 1 was separated and treated with MeI to give 2.
