Regioselective monotosylation of non-protected and partially protected glycosides by the dibutyltin oxide method

Tsuda,Nishimura,Kobayashi,Sato,Kanemitsu

, p. 2883 - 2887 (1991)

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
