Abstract
A recyclable, eco-friendly, efficient method of synthesis has been developed for the biologically active heterocycles pyranoquinolines and furanoquinolines via inverse electron demand Diels- Alder reaction mediated by choline chloride: zinc chloride ionic liquid as a catalyst and medium. The methodology offers the advantages such as mild reaction conditions, simple work-up procedure, highly efficient reaction, recyclable and eco-friendly catalyst etc. All the products were thoroughly characterized by FT-IR, 1H-NMR, 13C-NMR, Mass spectral and Elemental analysis.
