Polysulfonylated cyclodextrins. Part 11. Preparation and structural validation of three isomeric pentakis(6-O-mesitylsulfonyl)cyclomaltoheptaoses

Abstract

Three isomers of cyclomaltoheptaose derivatives, 1a–c, which possess five mesitylenesulfonyloxy groups on their C-6 atoms, were prepared. Assignment of the regiosiomers was performed by their conversion into compounds containing five 3,6-anhydroglucose units followed by 1H NMR analyses. The structures of the pentakis(3,6-anhydro) derivatives were also confirmed by their derivation from the known bis(TBDMS) derivatives.
