Improved synthesis of 1,3,4,6-tetra-O-acetyl-2-azido-2-deoxy-alpha-D-mannopyranose. By improved (anhydrous) work-up conditions of a triflate displacement reaction, the yield in the preparation of the versatile synthetic intermediate 1,3,4,6-tetra-O-acetyl-2-azido-2-deoxy-alpha-d-mannopyranose has been significantly enhanced. This important precursor is now available in three efficient steps from d-glucose.
