摘要
A simple and efficient method for the direct regioselective benzoylation of a single C-2 hydroxyl group of beta-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 benzoyl group migration.
