Abstract
A method for effective regiospecific preparation of 2A,2B-disulfonated γ-cyclodextrin has been developed. Reaction of γ-cyclodextrin with benzophenone-3,3′-disulfonyl imidazole and molecular sieves in DMF yielded 2A,2B-disulfonated γ-cyclodextrin with no 2A,2C-, 2A,2D-, 2A,2E-, 3-, or 6-sulfonyl isomers.
