An Efficient Synthesis and Antimicrobial Activity of 5-{2-[(1-Aryl-1H-1,2,3-triazol-4-yl)methoxy]-5-bromophenyl}isoxazoles

Resumo

A novel series of 1,2,3-triazolyl isoxazole derivatives is synthesized from the corresponding propargylated isoxazoles and a number of aryl azides by the Click reaction. The highest yields of the reaction are achieved in the presence of copper sulphate pentahydrate and sodium ascorbate, and using DMF:water (2:1) as a medium. The compounds structures are elucidated from various spectral data. Antimicrobial activity tests of the title compounds demonstrate their moderate to good results compared to the standard.
