In preceding articles',2, we have described stereoselective syntheses of nitropyrazolines by 1,3-dipolar cycloaddition of diazoalkanes to sugar nitro-olefins having the n-galacto and D-manno configurations. We now report the preparation of two new sugar nitro-olefins (5 and 6) bearing bromine as ano
