为了发现具有新型分子支架的绿色除草剂,使用天然四酸作为先导化合物来设计和合成四种结合了链状烷氧基烷基部分(4a–4d)和十九种吡咯烷-2,4-的吡咯烷-2,4-二酮衍生物。通过取代,酰化,环化和酸化反应掺入取代的苯氧乙基部分(10a-10s)的二酮衍生物。通过FT-IR,1 H NMR,13 C NMR和HRMS光谱分析确认了合成的目标化合物。化合物10a的单晶结构X-射线衍射分析表明,1-羟基亚乙烯基通过具有Z-构型的双键连接吡咯烷杂环的第三位置。通过培养皿培养法,以bar草(Echinochloa crus-galli)和油菜(Brassica campestris)为模型植物来评价除草活性。发现大多数目标化合物在100μgmL -1时对植物生长具有中等至良好的抑制活性。其中,化合物10q和10n对草和油菜幼苗的根系表现出最高的除草活性,相应的抑制率分别为65.6%和84.0%。该结果

Easily Accessible Auxiliary for Palladium-Catalyzed Intramolecular Amination of C(sp<sup>2</sup>)H and C(sp<sup>3</sup>)H Bonds at δ- and ε-Positions
for selectiveCH activation under palladium catalysis. The novel auxiliary showed its first powerful application in CH functionalization of remote positions. Both C(sp2)H and C(sp3)Hbonds at δ‐ and ε‐positions were effectively activated, thus giving tetrahydroquinolines, benzomorpholines, pyrrolidines, and indolines in moderate to excellent yields by palladium‐catalyzed intramolecular CH amination
The present invention provides compounds and compositions thereof which are useful as inhibitors of plasma kallikrein and which exhibit desirable characteristics for the same.
Novel 1-(4-substituted phenyl)-1H-imidazoles and their use as antiarrhythmic, anti-hypertensive and anti-ischemic agents is described. Pharmaceutical formulations containing such compounds are also discussed.
