Article abstract of DOI:10.1248/cpb.39.2883

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
