Molecular iodine catalyzed synthesis of tetrazolo[1,5-a]-quinoline based imidazoles as a new class of antimicrobial and antituberculosis agents

Abstract

Abstract A series of some new tetrazolo[1,5-a]quinoline based tetrasubstituted imidazole derivatives 6a–l have been synthesized by a reaction of tetrazolo[1,5-a]quinoline-4-carbaldehyde 3a–d, benzil 4, aromatic amine 5a–c and ammonium acetate in the presence of iodine through one-pot multi-component reaction (MCR) approach. All the derivatives were screened for antimicrobial and antituberculosis activities and results worth further investigations.
