Palladium-Catalyzed Intermolecular Coupling of Aryl Chlorides and Sulfonamides under Microwave Irradiation
摘要:
An efficient intermolecular N-arylation of sulfonamides with aryl chlorides is realized using palladium catalysis. The reaction proceeds under microwave irradiation at 180-200 degreesC for 10 min with 2-10 mol % of Pd catalyst in 32-85% isolated yields.
The C–H annulation of the five-position of quinolines and acrylates to afford heterocycles is an active field of research in organic synthesis. Herein the annulation of 4-aminoquinolines with acrylates through two consecutive C–Hactivations catalyzed by Rh(III) is described. The reaction proceeds with high atom efficiency under mild reaction conditions, and this protocol will provide appealing strategies
