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.
An efficient method for the construction of dibenzo[b,d]azepines containing two distinct stereogenic elements in a highly diastereoselective fashion is described. The key of the [5 + 2] reaction is to form a π-allylpalladium species through sequential C–H activation and regiospecific migratory insertion of the diene. This observation contrasts with the behavior of 1,2-alkenes that generally underwent
