Abstract
Quinolines and its derivatives are significant class of heterocyclic compounds which are identified as the key component in many natural products and biologically important molecules. We describe herein a facile method for the synthesis of quinoline derivatives from Morita-Baylis-Hillman (MBH) Alcohols via Palladium Catalyzed intramolecular aryl amination followed by allylic amination pathway. The reaction between a series of MBH alcohols and amino compounds (Tosyl, aliphatic and aromatic amines) under optimized reaction conditions with Pd(PPh3)2Cl2/DPPP catalyst system, afforded the corresponding 1,2-dihydroquinolines upto 95 % isolated yield.
