Reaction of Ammonia with Some Acetylated and Benzoylated Monosaccharides. IX. The Migration of Benzoyl Groups in the Ammonolysis of 1,2,3,4,6/Penta-O-benzoyl-D-galactoses
By ammonolysis of 1,2,3,4,6/penta-O-benzoyl-d-galaetoses, having labeled benzoyl groups at different carbon atoms, the following contributions of each benzoyl group to the formation of 1, 1/bis(benzamido)/1/deoxy-d-galactitol have been found: C/2, 0.13; C/3, 0.62; C/4, 1.02; C/6, 0.18 moles per mole...

| Sumario: | By ammonolysis of 1,2,3,4,6/penta-O-benzoyl-d-galaetoses, having labeled benzoyl groups at different carbon atoms, the following contributions of each benzoyl group to the formation of 1, 1/bis(benzamido)/1/deoxy-d-galactitol have been found: C/2, 0.13; C/3, 0.62; C/4, 1.02; C/6, 0.18 moles per mole. Compared with the penta-O-benzoyl-d-glucoses, the most interesting variation is the increase of the contribution of the benzoyl group at C/4, from 0.82 in the d-glucose series to total migration in the D-galactoses, that takes place at the expense of the contribution of the benzoyls in C/3 and C/6. © 1964, American Chemical Society.
