The read more title compound, C20H26O7, was prepared by esterification of 2,3;5,6-di-O-isopropylidene-α-d-mannofuranose with phenylacetic acid under standard DCC/DMAP (DCC = dicyclohexylcarbodiimide and DMAP = 4-dimethylaminopyridine) conditions.The solid-state structure confirms the retention of the α-configuration at the anomeric C atom.The compound is characterized by a relatively rigid framework with only a few degrees of freedom.Comparison with other di-O-isopropylidenemannofuranose derivatives shows the main differences to be associated with the flexible dimethyldioxolane ring, and that there are only small differences for click here the 2,3-O-isopropylidene-α-d-mannofuranose backbone.

The packing is marked by a large number of weak C—H.O interactions.
