Effects of CoCl2 on the regioselective tosylation of oligosaccharides

I'm happy to share with you a published article in which we have highlighted the effect of cobalt (II) chloride on the regioselectivity of tosylation of oligosaccharides. in this work, we have developed a methodology for the regioselective tosylation and we have tested the versatility of the method on different disaccharides and trisaccharides.
