Abstract
A convenient synthesis of some new 1,4-disubstituted 1,2,3-bistriazoles (3a–3f, 4a–4f, 6a–6b, 7a–7b) is reported via copper(I)-catalyzed Huisgen 1,3-dipolar cycloaddition of various terminal alkynes with 1,4-bis(azidomethyl)benzene and 1,6-diazidohexane. The synthesized compounds were characterized by spectral techniques including infrared, 1H NMR, 13C NMR, and high-resolution mass spectrometry and tested in vitro for antimicrobial potential against Bacillus subtilis and Staphylococcus aureus (Gram-positive bacteria), Pseudomonas aeruginosa and Escherichia coli (Gram-negative bacteria), and Candida albicans and Aspergillus niger (fungi). Among the synthesized 1,4-disubstituted 1,2,3-bistriazoles, compounds 6a, 6b, and 7b displayed excellent antimicrobial potential against most of the tested strains.
