two reaction sequences. The preferable method has allyl 3- O -allyl- d -glucopyranoside as key inter-mediate. This appears to be the first example of an anhydro sugar derivative with the 2,6-dioxabicyclo [3.1.1]heptane skeleton.
摘要通过对2,4,6-三-O-苄基-α-d-吡喃葡萄糖酰氯进行闭环合成了1,3-脱水-2,4,6-三-O-苄基-β-d-吡喃葡萄糖。两个反应序列。优选的方法以烯丙基3-O-烯丙基-d-吡喃葡萄糖苷为关键中间体。这似乎是具有2,6-二氧杂双环[3.1.1]庚烷骨架的脱水糖衍生物的第一个实例。
