## Abstract Sugar 1,2 thio ortho esters can be condensed with terminal glycosyl acceptors using iodonium‐ion sources (IDCP and NIS/TfOH) as activators. IDCP‐ or NIS/TfOH‐assisted glycosidation of sugar 1,2 thio ortho esters with primary hydroxyl groups of β€œarmed” or β€œdisarmed” ethyl (phenyl) 1‐thio

Recent studies from this laboratory revealed' that iodonium ion-mediated glycosylations of suitably protected alkyl I-thioglycosides showed great promise for the synthesis of antigenic oligosaccharides'. In evaluating the scope of this glycosylation method, we now report a stereoselective and high-y

## N-iodosuccinimide (ND) in the presence of an organic acid was found to be effective for the activation of fully acylated thioglycosides leading to J&trans linked esters. On the other hand, NIS together with a catalytic amount of tri#luoromethanesu&onic acid proved to be very convenient for the ra
