Based on the structure of lead compound of 7-hydroxy-4-methyl-coumarin, a series of novel fluorinated amide coumarin derivatives were designed and synthesized through the principle of bioactive substructure combination. Their structures were characterized by 1H NMR, 13C NMR and HRMS. N-(n-Butyryl)-N-(m-fluorobenzyl)-6-amino-7-methoxy-4-trifluo-romethyl-coumarin (f1) and N-(p-methylbenzoyl)-N-(m-fluorobenzyl)-6-amino-7-methoxy-4-trifluoromethyl-coumarin (f9) were further confirmed by X-ray single crystal diffraction. The results of herbicidal activity indicated that compounds f1, N-phenylacetyl-N-(m-fluorobenzyl)-6-amino-7-methyloxy-4-trifluoromethyl-coumarin (f13), N-methylacryloyl-N-(m-fluoro-benzyl)-6-amino-7-methoxy-4-trifluoromethyl-coumarin (f5), N-(cyclopropylcarbonyl)-N-(m-fluorobenzyl)-6-amino-7-meth-oxy-4-trifluoromethyl-coumarin (f7), N-(6-chloronicotinoyl)-N-(m-fluorobenzyl)-6-amino-7-methoxy-4-trifluoromethyl-cou-marin (f20), exhibited marked inhibition against the stem growth of Digitaria sanguinalis. And f9, f7, N-(naphthalene-2-carbonyl)-N-(m-fluorobenzyl)-6-amino-7-methoxy-4-trifluoromethyl-coumarin (f17) showed excellent inhibition on the stem of Chenopodium glaucum. The herbicidal activities of the compounds mentioned above were more active than the commercial herbicide acetochlor. The results of crop safety evaluation showed that compounds f1f9 and f13 were safe to Brassica pekinensis and Brassica napus but sensitive to Triticum aestivum and Sorghum bicolor. Furthermore, N-(m-bromobenzoyl)-N-(m-fluorobenzyl)-6-amino-7-methoxy-4-trifluoromethyl-coumarin (f12), f7 and f9 were medium active against the mycelium of phytopathogenic fungi Botrytis cinerea. And N-(hydrocinnamoyl)-N-(m-fluorobenzyl)-6-amino-7-methoxy-4-trifluoromethyl-coumarin (f14) was medium active to Valsa mali.
