Abstract
THE action of methanolic ammonia on methyl 2 : 3-anhydro 4 : 6-O-benzylidene-α-D-allopyranoside (I) followed by acetylation (pyridine – acetic anhydride) of the isolated amino-compounds yielded, as the major product (45.7 per cent), after recrystallization from aqueous-methanol, methyl 2-acetamido 4 : 6-O-benzylidene 2-deoxy-α-D-altropyranoside (II), melting point 188–189°, [M]D + 218° (acetone). (Found: C, 55.6, 55.8; H, 6.8, 6.7; N, 4.1. C16H21O6N.H2O requires C, 56.3; H, 6.7; N, 4.1 per cent).
