  2-amino-5-arylthieno[2,3-b]thiophenes has been synthesized regioselectively from the reaction of 5-aryldihydro-3(2H)-thiophenones with ethyl cyanoacetate/malononitrile and sulfur powder in the presence of morpholine under thermal as well as microwave irradiation conditions.

  A series of new substituted 1-(2-arylmethyl-5-aryl-3-thienyl)pyrrolidines and piperidines were synthesised by one-pot, three-component tandem reactions of 5-aryldihydro-3(2H)-thiophenone, aromatic aldehydes and pyrrolidine/piperidine under solvent-free microwave irradiation.

  A library of novel 5-amino-2,7-diaryl-2,3-dihydrobenzo[b]thiophene-4,6-dicarbonitriles have been synthesized regioselectively in good yields through the one-pot domino reactions of 5-aryldihydro-3(2H)-thiophenones, malononitrile and aromatic aldehydes in the presence of morpholine. This transformation presumably involves Knoevenagel condensation-Michael addition-intramolecular Thorpe-Ziegler cyclization-Tautomerization-Elimination sequence of reactions. These compounds were evaluated for their acetylcholinesterase (AChE) inhibitory activity and 5-amino-2,7-bis(4-methoxyphenyl)-2,3-dihydrobenzo[b]thiophene-4,6-dicarbonitrile was found to be the most potent against AChE with IC50 4.16 mu mol/L.

  A series of 2,9-diaryl-2,3-dihydrothieno[3,2-b]quinolines have been synthesized regioselectively by Friedlander annulation of 5-aryldihydro-3(2H)-thiophenones and 2-aminobenzophenones in the presence of trifluoroacetic acid in good yields under microwave irradiation at 100 degrees C. The 2,9-diatyl-2,3-dihydrothieno[3,2-b]quinolines were screened for in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv (MTB) and multi-drug resistant M. tuberculosis (MDR-TB). Among the 17 compounds screened, 7-chloro-2-(2,4-dichlorophenyl)-9-phenyl-2,3-dihydrothieno-[3,2-b]quinoline and 7-chloro-2-(3-nitrophenyl)-9-phenyl-2,3-dihydrothieno[3,2-b]quinoline display maximum activity with MIC of 0.90 and 0.95 mu M against MTB and MDR-TB respectively.
