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),
## Abstract D.n.m.r. studies have been performed involving the measurement of rates of __trans__β__cis__ isomerization of aliphatic enamino ketones of the type Rο£ΏCOο£ΏCHο£ΎCHο£ΏNHR~1~, by means of equilibration experiments and the method of finding the coalescence temperature.
