After that the“Vilsmeier salts”were synthesized from oxalyl chloride and 1,3-dimethyl-2-imidazolidinone ,then reacted with amino acid ethyl ester hydrochloride in dichloromethane.
首先我们采用了SOCl2法合成了L-氨基酸乙酯的盐酸盐,之后采用草酰氯法:即用1,3-二甲基-2-咪唑啉酮与草酰氯生成“vilsmeier salt”,再与L-氨基酸乙酯盐酸盐反应生成五烷基手性胍,最后用碘甲烷卤代生成六烷基手性胍卤盐。

结果表明,咪唑啉酮类除草剂在5~200μg/L(灭草喹在2.5~100μg/L)浓度范围内,标准曲线的线性相关系数范围为0.9987~0.9999;方法检出限(LOD)为0.0002~0.0005 mg/kg;在0.01、0.02、0.05 mg/kg(灭草喹在0.005、0.010、0.025 mg/kg)三个质量浓度添加水平,6种咪唑啉酮类除草剂平均加标回收率为81.6%~103.3%,相对标准偏差(RSD)为3.1%~8.3%。

咪唑啉酮衍生物具有杀菌、除草、杀虫等活性,是农用化学品研究开发最为活跃的研究领域之一。
Imidazolones, one of the most flourish in the research and development of agrochemicals, have been found to be used as herbicide, fungicide, etc.
研究了部分咪唑啉酮化合物的生物活性,结果表明此类化合物均未表现出明显的除草活性,但表现出抑菌活性。
The biological activities of partial imidazolones were studied. The results showed that they did not exhibit obviously herbicidal activity but fungicidal activity.
