2-C-Cyclohexyl-2,3-O-isopropylideneerythrofuranose

Abstract

In the title compound, C13H22O4, the acetonide ring adopts an envelope conformation with one of the O atoms as the flap atom, whereas a twisted conformation is found for the furanose ring. Centrosymmetric eight-membered {...OCOH}2 synthons involving the hydroxy H and acetonide O atoms are found in the crystal structure. These are linked into a supramolecular chain in the a-axis direction via C—H...O contacts.
