Abstract
Tosylation of γ-cyclodextrin in an aqueous alkaline solution gave two regiospecific isomers (2-monotosyl-γ-cyclodextrin(1) and 6-monotosyl-γ-cyclodextrin(2)), that could recognize and catalyze small sized guest molecules; 2-monotosyl-γ-CD recognized small sized guest molecules more effectively than did 6-monotosyl-γ-CD.
