Abstract Thirteen novel cyclic phosphates were rationally designed and synthesized by introducing diary ethers containing pyrimidine. All the target compounds were characterized by 1H, 13C, 31P NMR and HRMS. The test of herbicidal activity indicated that most of the compounds showed good herbicidal activities against Amaranthus retroflexus. The compounds IA-2 (1-(5,5-dimethyl-2-oxido-1,3,2-dioxaphosphinan-2-yl)propyl-2-((4
摘要 通过引入含有嘧啶的二元醚,合理设计合成了13种新型环状磷酸酯。所有目标化合物均通过 1H、13C、31P NMR 和 HRMS 进行表征。除草活性测试表明,大部分化合物对反枝苋表现出良好的除草活性。化合物 IA-2 (1-(5,5-二甲基-2-氧化-1,3,2-二氧膦-2-基)丙基-2-((4,6-二甲氧基嘧啶-2-基)氧基)苯甲酸酯) 和 IA-3 ((5,5-二甲基-2-氧化-1,3,2-二氧膦-2-基)(苯基)甲基-2-((4,6-二甲氧基嘧啶-2-基)氧基)苯甲酸盐)在 112.5 g ai/ha 的剂量下对测试的单子叶杂草表现出显着的紧急后除草活性。图形概要
