Crystal structure of 1-(2,3 : 5,6-Di-O-isopropylidene-beta-D-mannofuranosyl)-1H-[1,2,3]triazol-4,5-dicarboxylic acid diethyl ester

摘要

The synthesis and X-ray crystal structure of 1-(2,3:5,6-di-O-isopropylidene-beta-D-mannofuranosyl)-1H-[1,2,3]triazol-4,5-dicarboxylic acid diethyl ester are reported. It crystallizes in the orthorhombic system with space group P2(1)2(1)2(1) (No. 19); a=8.6148(5), b=10.4793(6), c=24.6873(15) angstrom and Z=4. The solid state structure verifies the beta-anomeric form of the title compound and provides evidence for the structures of the azide and chloride precursors.
