  .alpha.2-Adrenergic agonists/antagonists: the synthesis and structure-activity relationships of a series of indolin-2-yl and tetrahydroquinolin-2-yl imidazolines

  摘要：

  The synthesis and alpha 2-adrenergic activity of a series of indolin-2-yl and tetrahydroquinolin-2-yl imidazolines are described. The indolin-2-yl imidazoline 4b was found to possess potent alpha 2-adrenergic agonist and antagonist activity. The modification of the substituents on the indoline ring of 4b has led to the separation of these activities. Substitution on the aromatic ring of 4b with halogen or increasing the size of the N-alkyl substituent of 4b gave alpha 2-adrenergic antagonists without agonist activity. The N-allylindoline 4d is more potent than idazoxan in vitro and is equipotent in vivo, but is less receptor selective (alpha 2 vs. alpha 1) than idazoxan. The cis-1,3-dimethylindolin-2-yl imidazoline 6a is an alpha 2-adrenergic agonist equal in potency to clonidine in vitro, while the trans-1,3-dimethylindolin-2-yl imidazoline 6b is a moderately potent alpha 2-adrenergic antagonist.

  same lactone 3f product, demonstrating that this process may be deployed in a redox level-independent manner. A variety of substituted acrylic esters 2a-2h participate in spirolactone formation, as illustrated in the conversion of N-benzyl-3-hydroxyoxindole 1o to cycloadducts 4a-4h. Hydrohydroxyalkylation of hydroxyl-substituted methacrylate 2i with diols 1b, 1f, 1j, and 1l forms α-exo-methylene-γ-butyrolactones

  在钌(0)-催化的氢羟烷基化条件下，邻二醇1a-1l和丙烯酸甲酯2a以良好至极好的产率转化为相应的内酯3a-3l。丙烯酸甲酯 2a 与氢安​​息香 1f、安息香二脱氢-1f 和苄基四脱氢-1f 的反应形成相同的内酯 3f 产物，表明该过程可以以与氧化还原水平无关的方式部署。多种取代的丙烯酸酯 2a-2h 参与了螺内酯的形成，如 N-苄基-3-羟基吲哚 1o 向环加合物 4a-4h 的转化所示。羟基取代的甲基丙烯酸酯 2i 与二醇 1b、1f、1j 和 1l 的羟基烷基化形成 α-外型-亚甲基-γ-丁内酯 5b、5f、5j 和 5l，收率中等至良好。一个催化循环涉及 1, 假设 2-二羰基丙烯酸酯氧化偶联形成氧杂环戊二烯环中间体。通过单晶 X 射线衍射表征了具有催化能力的单核钌 (II) 配合物。使用对位取代的 1-苯基-1,2-丙二醇 1g、1m 和 1n 以及密度泛函理论计算，探讨了电子
