fungal metabolite and its (6S,7R,8S)-stereochemistry. Both synthetic PA and an analogue containing the 5-methylene-1,5-dihydro-2H-pyrrol-2-one nucleus exhibit μM inhibitory activity in root growth assays against Arabidopsis thaliana, indicating that this heterocyclic subunit is key to the herbicidal activity of the natural product.
首次报道了叶霉碱 A (PA) 的全合成,证实了这种真菌代谢物的结构及其 (6 S ,7 R ,8 S )-立体
化学。合成的 PA 和含有 5-methylene-1,5-dihydro-2 H -pyrrol-2-one 核的类似物在针对拟南芥的根生长试验中均表现出 μM 抑制活性,表明该杂环亚基是除草活性的关键的
