Synthesis and Characterization of N-(2,3,4,6-Tetra-O-acetyl-beta-D-glucopyranosyl)thiocarbamic 2,4-dihydroxy benzoyl hydrazine monohydrate

摘要

A new complex of N-(2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl)thiocarbamic 2,4-dihydroxy benzoyl hydrazine monohydrate,C_(22)H_(27_N_3O_(11)S centre dot H_2O,has been synthesized and its structure is determined by X-ray crystallography and TG/DTG.The compound crystallizes in the orthorhombic system,space group P432|2,with cell dimensions of a = 12.0199(7),b = 12.0199(7),c = 38.877(3)A,V = 5616.9(6)A~3 and Z= 8.The hexopyranosyl ring adopts a ~4C conformation.All the substit-uents are in equatorial positions.The molecules are linked into a three-dimensional framework by intermolecular interactions.The atoms O3,O7,O9 and C14 show positional disorders.
