Abstract
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 1 H 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. Com-pound 2l showed different degrees of herbicidal activity against A. theophrasti , A. spinosus L and C. album at 2250 g•ai/ha.
