Pd-Catalyzed Intramolecular Oxidative C–H Amination: Synthesis of Carbazoles
摘要:
A Pd-catalyzed oxidative C-H amination of N-Ts-2-arylanilines under ambient temperature using Ozone as an inexpensive, safe, and easy-to-handle oxidant has been developed. This process represents a green and practical method for the facile construction of carbazoles with a broad substrate scope and wide functional group tolerance.
Palladium-Catalyzed Oxidative Insertion of Carbon Monoxide to N-Sulfonyl-2-aminobiaryls through C–H Bond Activation: Access to Bioactive Phenanthridinone Derivatives in One Pot
摘要:
Palladium-catalyzed oxidative carbonylation of N-sulfonyl-2-aminobiaryls through C-H bond activation and C-C, C-N bond formation under TFA-free and milder conditions has been developed. The reaction tolerates a variety of substrates and provides biologically important phenanthrldlnone derivatives in yields up to 94%.
