Abstract
An efficient procedure for modification at C-2 position of fully methy lated alpha-, beta-, and gamma-cyclodextrins was achieved by thiolytic fission of one of their glycosidic bonds, followed by conversion of t he resulting 1-thioglycosides into glycals and addition of iodonium io n accompanied intramolecular glycosidation, giving novel methylated cy clooligosaccharides containing 2-deoxy-2-iodo-alpha-D-mannopyranosyl m oiety as one of the constituents.
