Abstract:Catalytic hydrogenation of a series of N-(pent- and hex-2-enopyranosyl)benzotriazoles afforded the corresponding saturated N-glycosyl derivatives having the same anomeric configuration as the starting compounds. The conformations of all compounds obtained were determined by nmr spectroscopy. The hexopyranosyl nucleosides in solution adopt the Cl conformation. On the other hand, pentopyranosyl nucleosides exist as a mixture of the two chair conformers in equilibrium, with the IC or CI ( L ) form predominating.
