Friedlander synthesis of poly-substituted quinolines in the presence of dodecylphosphonic acid(DPA)as a highly efficient,recyclable and novel catalyst in aqueous media and solvent-free conditions

摘要

Poly-substituted quinolines were synthesized in the presence of a catalytic amount of dodecylphosphonic acid(DPA)in aqueous media and solvent-free conditions.The reactions proceed very well under relatively mild conditions,and DPA can be recycled.
