benzoylation of a single C-2 hydroxyl group of β-cyclodextrin was developed by using a combination of N,N′-carbonyldiimidazole and carbonate buffer in 1,4-dioxane, which does not require highly reactive reagents such as acyl chloride, or toxic solvents such as acetonitrile. Moreover, hydrolysis of the product was determined to occur via benzoylgroupmigration. Graphical abstract
