The Iodine-mediated oxidative intramolecular amination of anilines via cleavage of unactivated (sp3)C–H and N–H bonds for the production of indolines is described. This transition-metal-freeapproach provides a straightforward strategy for producing (sp3)C–N bonds for use in the preferential functionalization of unactivated (sp3)C–H bonds over (sp2)C–H bonds. The reaction could be performed on a gram
Copper-catalyzed oxidativeintramolecularcyclization of o-alkylated anilines via cleavage of C(sp3)-H and N-H bonds for the production of indolines is described. This approach provides a straightforward strategy for the synthesis of nitrogen-containing heterocyclic compounds through the functionalization of unactivated C(sp3)-H bonds with high site selectivity. The present catalytic system shows high preference

By using diaryliodoniumsalts, a cylization has been accomplished in the synthesis of N-aryl phenanthridinone derivatives via a cascade of ortho-arylation and Csp2-N bond formation in the presence of palladium catalyst. The reaction exhibits a broad compatibility of readily available N-arylnaphthamides.
