Synthesis and insecticidal activity of novel benzothiazole derivatives containing the coumarin moiety
A series of novel benzothiazole derivatives containing a coumarin moiety was designed and synthesized. Their structures were characterized in detail via 1H NMR, 13C NMR, HRMS spectra and single-crystal X-ray diffraction analysis. The bioassay results indicated that some compounds showed encouraging insecticidal activity against Plutella xylostella and Aphis fabae at 400 mg/L. The preliminary structure-activity relationships were also discussed.
