摘要：

3(A)-Azido-3(A)-deoxy-altro-beta-cyclodextrin, although having as many as 20 different hydroxyl groups, was selectively sulfortylated at the 2(A)-OH of the altrose residue by 2-mesitylenesulfonyl chloride to give 3(A)-azido-3(A)-deoxy-2(A)-O-mesitylenesulfonyl-altro-beta-cyclodextrin. A one-pot reduction-intramolecular substitution of the latter afforded the title compound as a promising intermediate for the introduction of two different functional groups to two different positions of one sugar unit, which has not been succeeded hitherto.
