(-)-Benzyl 2,3-dide-oxy-?-d-erythro-hex-2-eno-pyran-oside.

ABSTRACT: In the title compound, C13H16O4, the six-membered ring of the sugar moiety shows a half-chair conformation. In the crystal, mol-ecules are connected via O-H?O hydrogen bonds, forming columns around twofold screw axes along the b-axis direction. There is a disorder of the benz-yloxy group, which has two possible orientations with the phenyl group lying on a common plane [site-occupancy factors = 0.589?(9) and 0.411?(9)].

In the title compound, C13H16O4, the six-membered ring of the sugar moiety shows a half-chair conformation. In the crystal, mol-ecules are connected via O-H⋯O hydrogen bonds, forming columns around twofold screw axes along the b-axis direction. There is a disorder of the benz-yloxy group, which has two possible orientations with the phenyl group lying on a common plane [site-occupancy factors = 0.589 (9) and 0.411 (9)]. ...[more]
