Direct synthetic access to glycosyl-1-phosphates is accomplished with the d
ehydrative coupling of carbohydrate hemiacetals and dialkyl phosphates, emp
loying 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 selecti
vity.
