Abstract

A novel and efficient synthesis of substituted pyranones and pyridinones is developed using cumene hydroperoxide as oxidant by vanadium-catalyzed Achmatowicz rearrangement and aza-Achmatowicz rearrangement reactions. It offers a sustainable and environmentally benign approach to access multisubstituted pyranones or pyridinones derivatives.
