Synthesis and Crystal Structure of 2,3,4,6-Tetra-O-acetyl-(β-D-glycosyl)-isothiocyanate

Abstract

Abstract: The title compound, 2,3,4,6-tetra-O-acetyl-(β-D-glycosyl)-isothiocyanate( C₁₅H₂₇·NO₉S), were synthesized and its crystal structure was characterized. It crystallizes in cubic system, space group P2₁2₁2₁ with the cell parameters a=1.294 3(3) nm, b=0.828 40(2) nm, c=1.514 8(3) nm, V=1.623 9(6) nm³, Z=4. The hexopyranosyl ring adopts a normal ⁴C₁ chair conformation with total puckering amplitude, Q_T of 0.606.
