Chiral benzazaborole-catalyzed regioselective sulfonylations of unprotected carbohydrate derivatives have been developed. This methodology enables direct regioselective functionalization of the secondary OH group in carbohydrate in the presence of the primary OH group. By using the chiral organoboron catalysis, kinetic resolution of the carbohydrate derivatives was also achieved.
Regioselective monotosylation of non-protected and partially protected glycosides by the dibutyltin oxide method

Tosylation of non-protected glycopyranosides with p-toluenesulfonyl chloride in the presence of 4-dimethylaminopyridine, after activiation of the glycosides by dibutyltin oxide, gave mono-O-tosylates in good yield. The regioselectivity in this tosylation
