A series of herbicidal molecules derived from 3-acetyl-4-hydroxy-5-sec-butylpyrroline-2-ketone, a natural substance, and their potential use in agriculture for weed control. Through the modification of the 5-sec-butyl hydrocarbon chain and 3-acetyl group and the analysis of their biological functioning, newly designed molecules are superior to the original compound in herbicidal activity. These molecules inhibit the photosynthesis of the plants. The treated plants show significant damage in 24 hours and die within 3-5 days after the chemical treatment. In addition, the new molecule has relatively simple structure, they are easy to make and they have better physical properties. They are broad-spectrum, high potency herbicides.
从天然物质3-乙酰基-4-羟基-5-sec-丁基吡咯烷-2-酮衍生出的一系列除草分子及其在农业中用于除草的潜在用途。通过对5-sec-丁基烃链和3-乙酰基的改造以及对它们生物功能的分析,新设计的分子在除草活性方面优于原始化合物。这些分子抑制了植物的光合作用。处理后的植物在化学处理后的24小时内显示出明显的损伤,并在3-5天内死亡。此外,新分子具有相对简单的结构,易于制备,并具有更好的物理性质。它们是广谱、高效的除草剂。
