Studies on Pyridine Derivatives (Ⅺ):Synthesis and Herbicidal Activities of Both Enantiomers of 2-sec-Butylamino-5-(2-chloropyrid-4-yl)-1,3,4-thiodiazoles
摘要
Abstract
Both enantiomers of 2-sec-butylamino-5-(2-chloropyrid-4-yl)-1,3,4-thiodiazoles (BCPT),a powerful racemic herbicidal compound which was found in previous research,were synthesized from R-and S-butylamine respectively. The preliminary bioassay results showed that three of the thiodiazoles (racemate and enantiomers) were excellent growth inhibitors to both roots and stems of barnyard grass.The S-( + ) enantiomer was the strongest for stem growth inhibition,and R-(-) enantiomer was the weakest. But they had little inhibiting difference on root growth.关键词
