We herein disclose a simple and general method for the synthesis of chromendiones through Rh(III)-catalyzed C−H functionalization/annulation reactions of nitrones with cyclic 2-diazo-1,3-diones by using nitrone group as a traceless directing group. This method exhibits high efficiency and broad functional group compatibility. The derivatization of these chromendiones has been also demonstrated to further
