【Abstract】 Nine Schiff bases of 3-amino-dihydrothiophene-2-one were synthesized by reaction of substi-tuted benzaldehyde with DL-homocysteine thiolactone hydrochloride by means of preferable reaction condi-tions. Seven of them were reported for the first time. The structures of the compounds were confirmed by elemental analysis, 1H NMR and IR spectra. The biological tests showed that they were excellent biological active to several vegetable pathogen.更多还原
