The synthesis and X-ray analysis of the title compound is described. The peracetylated benzyl fucopyranoside derivative was prepared by following the classical KoenigsKnorr methodology. The X-ray diffraction analysis showed a monoclinic system, with a = 9.7834(5) Å, b = 10.4653(6) Å, c = 10.0752(6) Å, space group P21, and = 100.1820(1). Expected 4C1 conformation was observed for the fucoside ring and benzyl group, which were oriented toward an equatorial position. Endocyclic angle C1O5C5 was in agreement with the geometry of equatorial glycoside bonds, typical for -D-4C1 pyranoside conformation.
