We have disclosed 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 nitrones as a traceless directing group. This method shows high efficiency and wide functional group compatibility. The derivatization of these chromendiones has also been demonstrated to enhance the synthetic utility of the transformation.
