  Mesoporous mixed metal oxide nanocrystals: Efficient and recyclable heterogeneous catalysts for the synthesis of 1,2-disubstituted benzimidazoles and 2-substituted benzothiazoles

  摘要：

  Present communication elicits the use of mesoporous mixed metal oxide nanocrystals of Al2O3-Fe2O3. Al2O3-V2O5 and Al2O3-CuO as heterogeneous catalysts for the preparation of series of medicinally significant 1,2-disubstituted benzimidazoles and 2-substituted benzothiazoles. These nanocrystalline catalysts exhibited remarkable catalytic activity with a high substrate to catalyst weight ratio (20:1) to achieve the synthetic targets in the range of yield 81-96%. The solvent-free microwave assisted synthesis of these compounds was an advantageous way which resulted in excellent yields in much lesser time (0.75-1.5 min) in comparison to conventional heating. The use of catalyst in eco-friendly green protocol and its reusability up to four cycles with similar catalytic response are the unique features of the heterogeneous catalysis. This protocol provided greater selectivity, cost-efficiency, clean reaction profiles, simple work-up procedure and high yields. (C) 2011 Elsevier B.V. All rights reserved.

  Present communication deals with the in vitro time point quantitative antibacterial evaluation of newly synthesized 1,2-disubstituted benzimidazoles (3a-p) and 2-substituted benzothiazoles (5a-h) against Gram-positive bacteria Staphylococcus aureus, Bacillus cereus, and Gram-negative bacteria Vibrio cholerae, Shigella dysenteriae and Escherichia coli. These compounds were synthesized under mild reaction conditions using Al(2)O(3)-Fe(2)O(3) nanocrystals as heterogeneous catalyst. Bio-evaluation studies revealed that, compounds 3a, 5a and 5d exhibited moderate to good antibacterial activity against all the tested bacterial stains. The compounds 3a, 3f and 5a have shown enhanced inhibitory activity compared with standard antibacterial drug ciprofloxacin against V. cholerae, B. cereus, and S. dysenteriae, respectively. Additionally, the compounds 3a, 3e, 3f, 3h and 5b displayed complete bactericidal activity within 24 h, whereas ciprofloxacin took 48 h to kill those bacteria completely. (C) 2011 Elsevier Ltd.
