Benzothiadiazine-1,1-dioxide scaffold is bioactive framework with wild utility and applications. Synthesis of benzothiadiazine-fused isoquinoline derivatives and spiro benzothiadiazine derivatives through transition metal-catalyzed C—H activation/annulation was reported. 3-Phenyl-2H-benzothiadiazine-1,1-dioxide was used as the reaction substrate, and vinylene carbonate and 4-diazopyrazolone were used as the coupling
