1,4-Disubstituted-1,2,3-triazoles (3–27) have been synthesized by [3+2] cycloaddition of different 2-(azidomethyl)-dihydronaptho(benzo)furans (2a, 2b, 2c and 2d) with different alkynes. All the compounds were screened for antitubercular activity against Mycobacterium tuberculosis H37Rv. Compounds 2a, 7, 9, 12 and 14 exhibited antitubercular activities with MIC ranging from 12.5 to 3.12 μg/ml.
1,4-二取代-1,2,3-三唑(3 – 27)是通过不同的2-(叠氮甲基)-二氢萘(苯并)呋喃(2a,2b,2c和2d)的[3 + 2]环加成合成的与不同的炔烃。筛选所有化合物针对结核分枝杆菌H 37 Rv的抗结核活性。化合物2a中,7,9,12和14种与MIC显示抗结核活性范围从12.5至3.12微克/毫升。
