Tartaric acid was employed as a naturally green catalyst for economical and facile preparation of polysubstituted quinolines via Friedländer hetero-annulation/condensation, 12-aryl-tetrahydrobenzo[α]xanthene-11-ones, 1,8-dioxo-octahydroxanthenes and 14-aryl-14Hdibenzo[α,j]xanthenes in solvent-free, one-pot multi-component reactions. This environmental friendly protocol provides high to excellent yields, short reaction times, clean reactions, simplicity and easy work up and mild conditions compared to the traditional method of synthesis. Furthermore, naturally green, low-cost and non-toxic catalyst made this protocol economic and sustainable.
