Abstract
Here, we report the novel synthesis of N-(acyloxy)phthalimides and their analogues as redox-active esters in the presence of propylphosphonic anhydride (T3P®) reagent using 2-methyltetrahydrofuran as a green solvent under mild reaction conditions. Our convenient technique provides a chromatography-free access to these remarkable synthetic intermediates with a wide substrate scope. By using our synthetic method, a variety of alkyl, aryl, arylalkyl and heteroaryl derivatives have been prepared.
