2,6-Anhydro-1,3-di-O-benzyl-d-mannitol

Abstract

In the title compound, C20H24O5, the six-membered pyranose ring adopts a chair conformation. The dihedral angle between the planes of the phenyl groups of the benzyl substituents is 63.1°. Two types of intermolecular O—H...O hydrogen bonds lead to the formation of infinite chains along the b axis. Only weak C—H...O contacts exist between neighboring chains.
