Ametoctradin is a new Oomycete-specific fungicide under development by BASF. It is a potentinhibitor of the bc1 complex in mitochondrialrespiration. However, its detailed action mechanism remains unknown. In the present work, the binding mode of ametoctradin was first uncovered by integrating molecular docking, MD simulations, and MM/PBSA calculations, which showed that ametoctradin should be a Qo
A cascade process for the straightforward one-pot conversion of β-ketonitriles into β-hydroxyamides is presented. The process, that proceeds in water employing the arene-ruthenium(II) complex [RuCl2(η6-p-cymene)P(4-C6H4F)2Cl}] as catalyst in combination with sodium formate, involves the initial hydration of the β-ketonitrile substrates to generate the corresponding β-ketoamide intermediates, which
提出了一种简单的一锅法将β-乙腈转化为β-羟酰胺的级联方法。的过程中,在水中进行采用芳烃-钌(II)络合物将[RuCl 2(η 6 - p -cymene)P(4-C 6 H ^ 4 F)2氯}]如甲酸钠催化剂组合该方法涉及β-酮腈底物的初始水合反应,以生成相应的β-酮酰胺中间体,然后对其进行羰基的转移氢化(TH)。雇用40个不同的β族-乙腈具有不同的取代模式,已经确定了该方法的范围和局限性。
