Abstract A number of aldono-1,4-lactones have been converted to their perbenzylated derivatives by treatment with benzyl trichloroacetimidate. 2,3,6-Trideoxy- d - erythro -hexono-1,4-lactone could be benzylated in dichloromethane, but lactones containing two or more hydroxy-groups were insoluble and could therefore not be benzylated in this solvent. It has now been found that the benzylation can be
摘要通过三氯乙亚氨酸苄酯处理,将许多aldono-1,4-内酯转化为过苄基衍生物。2,3,6-三甲氧基-d-赤-己基-1,4-内酯可以在二氯甲烷中被苄基化,但是含有两个或多个羟基的内酯是不溶的,因此不能在该溶剂中被苄基化。现已发现,苄基化可以在二恶烷中进行,并且使用该溶剂,以良好的收率制备了许多过苄基化的内酯,包括四-O-苄基-d-半内酯-1,4-内酯。
