Abstract

The title compound, C(19)H(26)O(8)S, has been synthesized from 2,3:4,5-di-O-isopropyl-idene-β-d-fructopyran-ose. The absolute configuration of the fused ring is confirmed by anomalous dispersion effects in the diffraction measurement. The six-membered β-fructopyran-ose ring has a twist-boat conformation with the two five-membered rings trans to each other. In the crystal, inter-molecular non-classical C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

摘要

标题化合物C(19)H(26)O(8)S由2,3:4,5-二-O-异亚丙基-β-D-呋喃果糖合成。稠环的绝对构型通过衍射测量中的反常色散效应得以确定。六元β-呋喃果糖环具有扭船构象,两个五元环彼此反式排列。在晶体中,分子间非经典的C-H⋯O氢键将分子连接成三维网络。
