[reaction: see text] Direct synthetic access to glycosyl-1-phosphates is accomplished with the dehydrative coupling of carbohydrate hemiacetals and dialkyl phosphates, employing dibenzothiophene-5-oxide and triflic anhydride. The procedure offers a new and versatile method for efficient preparation of a host of glycosyl-1-phosphates of variable structure with good control over anomeric selectivity
[反应:见正文]通过使用糖类半缩醛和磷酸二烷基酯的脱水偶联,使用二苯并噻吩-5-氧化物和三氟甲磺酸酐,可以直接合成获得糖基-1-磷酸酯。该方法提供了一种新的通用方法,可有效制备具有可变结构且对端基选择性具有良好控制的多种糖基-1-磷酸糖基。
