Ammonolysis and azidolysis of four benzyl 2,3-anhydro-4-azido-4-deoxypentopyranosides of α-d-lyxo, α-d-ribo, β-l-lyxo, and β-l-ribo configurations, were studied. Ratios of two ring-opening isomers and relative reaction rates were determined, factors controlling the direction of ring opening being discussed.
