Both 'H-and 13C-n.m.r. spectroscopy have been employed in structural studies of the 4,6-O-benzylidene-D-aldohexopyranosides and derivatives, including some deoxy sugars . I4 We now report i3C-n.m.r. data (Table I) for the 4,6-O-benzylidene derivatives of methyl 2-deoxy-( 2) 2-deoxy-3-O-methyl-(3),
The sulfation of dermatan sulfate by SO3-trimethylamine in N,N-dimethylformamide led to substitution initially at HO-6 of residues of 2-acetamido-2-deoxy-beta-D-galactopyranosyl 4-sulfate (1), to produce the 4,6-disulfate (6). When this step reached a level of greater than 50%, sulfation occurred wi
