A reaction of β-cyclodextrin with β-naphthylsulfonyl chloride in alkaline aqueous acetonitrile gave only one isomer (3A,3C,3E-trisulfonate, 17.8percent) of five 3,3,3-tri-O-sulfonyl-β-cyclodextrins.The isomer was converted to 3A,6A:3C,6C:3E,6E-trianhydro-β-cyclodextrin, the structure of which was assigned by comparing its spectral and HPLC data of the trianhydro-β-cyclodextrin with those of all authentic 3,6:3,6:3,6-trianhydro-β-cyclodextrins prepared by the reactions of known 6-tri-O-sulfonylated β-cyclodextrins with aqueous alkali.
