Abstract

X-ray crystallography unequivocally showed that protection of the free hydroxyl group of 3,5-O-benzyl-idene-d-lyxono-1,4-lactone with diphenyl-diazo-methane proceeded with retention of configuration to give the title compound, C(25)H(22)O(5). The crystal structure consists of layers of inter-locked mol-ecules lying parallel to the a axis.

摘要

X射线晶体学明确表明，用二苯基重氮甲烷保护3,5-O-亚苄基-d-来苏糖-1,4-内酯的游离羟基时构型保持不变，得到标题化合物C(25)H(22)O(5)。晶体结构由平行于a轴排列的互锁分子层组成。
