[RuCl2(dppf)(PN)]/Pd-cocatalyzed three-component synthesis of 2-pyridinyl-6-arylquinolines

Abstract

Abstract A new complex [RuCl2(dppf)(PN)] 1 (dppf = 1,1′-bis(diphenylphosphino) ferrocene; PN = (2-diphenylphosphino)benzenamine) has been synthesized and characterized. Its structure was determined by single-crystal X-ray diffraction. An efficient 1/Pd salt-cocatalyzed three-component oxidation/cyclization/Suzuki reaction for the synthesis of 2-pyridinyl-6-arylquinolines from 2-acetylpyridine, (2-amino-5-bromophenyl)methanol, and arylboronic acids has been developed.
