Synthesis of some Novel Piperidone linked Bisquinolines

B. Praveen Kumar, S. Venkataraman, R. Meera and P. Devi

Some novel piperidone linked bisquinolines were synthesized efficiently in 2 steps. In step I, 6- substituted-2-chloro-3-formyl quinolines were prepared by Vilsmeir-Heark reaction. The compounds so formed in step I were treated with ammonium acetate and different ketones in alcohol to yield required piperidone linked bisquinolines. The synthesized compounds were identified by FTIR, 1 H and 13NMR spectroscopic techniques.
