Rh(III)-Catalyzed Oxidative Coupling of N-Aryl-2-aminopyridine with Alkynes and Alkenes
摘要:
[RhCp*Cl-2](2) (1-2 mol %) can catalyze the oxidative coupling of N-aryl-2-aminopyridines with alkynes and arylates to give N-(2-pyridyl)indoles and N-(2-pyridyl)quinolones, respectively, using Cu(OAc)(2) as an oxidant. Coupling with styrenes gave mono- and/or disubstituted olefination products.
