title: 1-Dibenzylamino-1-de-oxy-4,5-O-isopropyl-idene-β-d-fructopyran-ose.
abstract: The title compound C(23)H(29)NO(5), synthesized by the Amadori rearrangement of α-d-glucose with dibenzyl-amine and the ketalization, is shown to be a β-anomer. The fructopyran-ose ring adopts a chair conformation. The two benzene rings form a dihedral angle of 68.9 (1)°. In the crystal, non-classical inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
