A rapid method for the preparation of N-aryl-2-methylthio-4-oxo-1,4-dihydro quinoline-3-carbonitriles (2a–e) and N-aryl-3-methylthio-4H-1,4-benzothiazine-2-carbonitrile 1,1-dioxides (2f–o) is reported. The cyclization is accelerated by microwave irradiation under solvent free conditions in the presence of K2CO3.

AbstractNew thiazole-substituted dibenzofurans 7a–j were synthesized from dibenzofuran derivatives 5a–b and substituted thiosemicarbazones 6a–h under conventional and microwave irradiation conditions. The structures of all products were established on the basis of analytical and spectral data. The synthesized compounds were evaluated for their in vitro antibacterial activity against Gram-positive and Gram-negative strains. Compounds 7b, 7d and 7h are active against Bacillus subtilis (+ve), and compound 7i displays good activity against Pseudomonas aeruginosa (-ve) strain. Compounds 7a–j were also evaluated for their in vitro antimycobacterial activity, and compound 7b shows antimycobacterial activity against Mycobacterium bovis strain.
