Activated bentonite promoted Friedländer condensation reactions: Synthesis of thieno[2,3-b]quinolinones and tacrines analogues derivatives Dridi, Khaireddine Mohamed Said, Ridha Ben Arfaoui, Youssef Al-Ayed, Abdullah Sulaiman Ketones Bentonite Tacrine analogues Friedlander reaction 2-Aminothiophene-3-carbonitrile 4-Aminothieno[2 3-b]quinolinones Some new aminothieno[2,3-b]quinolinones and tacrine analogues derivatives were synthesized in high yield with acid activated bentonite as a catalyst via the Friedländer condensation reactions between 2-aminothiophene-3-carbonitrile and ketones. The structure elucidation of compounds was done by FT-IR, NMR spectroscopy and microanalytical elemental data.
