- Sugar Tosylates via p-Toluenesulfinic Acid Esters. - p-Toluenesulfinimidazolide - A Reagent for Formation of Sulfinic Acid Esters without Using Halides
-
The reaction of the protected sugar derivatives 1, 4, 7, 10, 13, 16, 19 and 20 with p-toluenesulfinimidazolide prepared from p-toluenesulfinic acid and N,N'-carbonyldiimidazole yields the corresponding p-toluenesulfinic esters 2, 5, 8, 11, 14, 17, 20 and 22.With the exception of 20 and 22, these products can be oxidized with m-chloroperbenzoic acid in high yields and short overall reaction times to the tosylates 3, 6, 9, 12, 15 and 18.
