4-Sulfenyl-2-carbamoyl-4-isoxazolin-3-ones (4) were designed on the basis of biological isosterism and prepared in four steps. Some of these compounds showed sufficient pre-emergent herbicidal activities against various kinds of weeds. Among the synthesized compounds, 2-(N-(4-chlorophenyl)-N-isopropylcarbamoyl)-4-ethyl-thio-5-methyl-4-isoxazolin-3-one (4cd) exhibited the most promising activity.
根据生物异构原理设计了 4-亚磺酰基-2-氨基甲酰基-4-异噁唑啉-3-酮(4),并分四个步骤制备。其中一些化合物对多种杂草具有充分的萌前除草活性。在合成的化合物中,2-(N-(4-氯苯基)-N-异丙基氨基甲酰基)-4-乙硫基-5-甲基-4-异噁唑啉-3-酮(4cd)表现出最有前途的活性。
