Sixteen (E)-2-benzylidenimino-4-(7-methoxy-2,2-dimethyl-2,3-dihydrobenzofuran-5-yl)thiazoles were synthesized from 2,3-dihydro-2,2-dimethyl-7-benzofuranol by etherification, Friedel-Crafts acylation, α-bromation, cyclization of thiazole and imidization. Their structures were clearly established by 1H NMR, MS spectra and elemental analysis. The preliminary bioassays indicated that compounds 2a and 2i exhibited insecticidal activity against T. urticae were 53.10% and 67.71% at 500 mg/L. Compounds 2a and 2k exhibited fungicidal activity against S. sclerotiorum were 57.9% and 59.8% at 25 mg/L. Compound 2l showed different degrees of herbicidal activity against A. theophrasti, A. spinosus L and C. album at 2250 g·ai/ha.

Key words: (E)-2-benzylidenimino-4-(7-methoxy-2,2-dimethyl-2,3-dihydrobenzofuran-5-yl)thiazole, synthesis, insecticidal activity, fungicidal activity, herbicidal activity
