Abstract
The equilibrium
compositions of 1-deoxy-D-fructose, 1-deoxy-L-sorbose, 1-deoxy-L-psicose, D-threopentulose,
D-arabino-
and L-xylo-3-hexulose and coriose in aqueous solution have been determined by 13C
N.M.R. spectroscopy. In all but the last case, considerable amounts of the
acyclic keto form are present at equilibrium. The hydrated keto form was not
detected; a model compound, l-deoxy- 3,4,5,6-tetra-O-methyl-D-fructose, was found not to be
hydrated in aqueous solution.
