architecture. The synthesis of new analogues was achieved by FeCl3 mediated one pot three component condensation of 2-nitrovinylcarbazoles with aryl or alkyl amines and dimethylacetylene dicarboxylate (DMAD). All the new analogues 5a–l and 6a–l were fully characterized by their NMR and mass spectral data. Among the twenty four new compounds screened for in vitro anti-mycobacterial activity against Mycobacterium
