A new stereospecific method for 1,2- cis-glycosylation

A new stereospecific method for 1,2- cis-glycosylation involves the reaction of 1,2- trans-glycosyl thiocyanates with sugar trityl ethers in the presence of triphenylmethylium perchlorate. The method has been applied to give disaccharide derivatives with (1→6), (1→4), (1→3), and (1→2) linkages....
