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.
