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----3), and (1----2) linkages.
