Iodonium ion-assisted glycosylation of alkyl (aryl) 1-thio-glycosides: Regulation of stereoselectivity and reactivity

Article abstract of DOI:10.1016/0008-6215(91)84036-E

We report a stereoselective and high-yielding approach toward the synthesis of an appropriately protected 1,2-cis-linked disaccharide which is a key intermediate in the preparation of the tetrasaccharide hapten from the glycopeptidolipid antigen of Mycobacterium avium serotype 4.
