Synthesis and biological evaluation of novel saccharin derivatives containing 1,2,3-triazole moiety

A series of novel saccharin derivatives containing 1,2,3-triazole moiety was synthesized in satisfactory yields. The structures of all the compounds were elucidated and confirmed by Fourier transform infrared(FTIR) spectroscopy, 1 H and 13 C nuclear magnetic resonance( 1 H NMR, 13 C NMR) spectroscopy, and high resolution mass spectrometry(HRMS). The bioassays indicated that most of the title compounds displayed some extent herbicidal activities at 100 μg/mL.
