An efficient and operationally simple method for the synthesis of α-acyloxy ketones through readily available 2-methylimidazole-promoted reaction α-hydroxy anhydrides is developed. In reaction, act as both a substrate solvent. The new features good tolerance, mild conditions, accessible starting materials, excellent yields, providing facile green access to targets. Importantly, also avoids use reagents with pungent odors, such pyridine, in traditional esterification, which may promote development organocatalysis using nitrogen-containing heterocyclic compounds catalysts.
