regioselective with respect to the position of the C–H bond activation due to the directing effect of the amide group. In the same way, the synthesis of fused heterocycle-pyrones (isocoumarins) has been developed by Ru-catalysed oxidative coupling of heterocyclic carboxylic acids and internal alkynes. The reaction involves C–H and O–H bond activation. This reaction also has a broad scope, from electron-rich
