Henry cyclization

WebPeriodate oxidation of 6 followed by internal Henry cyclization and borohydride reduction gave 6-benzamido-9- (3-deoxy-3-nitro-α- L -ribofuranosyl)purine ( 10) which upon catalytic hydrogenation and subsequent de- N -benzoylation produced the title compound, 12. The sensitivity of certain nitro intermediates towards alkali is commented upon. Résumé WebJournal of the Chinese Chemical Society 62(10): 843-849
