  Structure−Activity Relationships in a Series of Bisquaternary Bisphthalimidine Derivatives Modulating the Muscarinic M₂-Receptor Allosterically

  摘要：

  Hexane-bisammonium-type compounds containing lateral phthalimide moieties are well-established ligands of the common allosteric binding site of muscarinic M-2 receptors. Previous structure-activity relationships (SAR) revealed two positively charged centers and two lateral phthalimide moieties in a defined arrangement to be essential of a high allosteric potency. The purpose of this study was to replace one carbonyl group of the phthalimides with hydrogens, hydroxy, alkoxy, phenyl, benzyl, and benzylidene groups in order to check the influence of these substituents on the allosteric activity in antagonist-linked receptors. The analysis of the quantitative SAR indicated that a high allosteric potency is related to a certain amount of rigidity as well as polarizibility and the ability to form hydrophobic interactions.

  The synthesis of various 3-arylmethylene-2,3-dihydro-1H-isoindolin-1-ones was realized following a simple three-step process. The protocol utilized the photodecarboxylative addition of readily available carboxylates to N-(bromoalkyl)phthalimides as a versatile and efficient key step. The initially obtained hydroxyphthalimidines were readily converted to the desired N-diaminoalkylated 3-arylmethylene-2

  通过简单的三步过程即可实现各种3-芳基亚甲基-2,3-二氢-1H-异吲哚-1-酮的合成。该协议利用了容易获得的羧酸酯的光脱羧加成到N-（溴代烷基）邻苯二甲酰亚胺的通用有效步骤。最初获得的羟基邻苯二甲酰亚胺通过酸催化的脱水作用随后被相应的仲胺亲核取代，可以很容易地转化为所需的N-二氨基烷基化的3-芳基亚甲基-2，3-二氢-1H-异吲哚-1-酮。该程序已成功应用于中性形式的已知局部麻醉药（AL-12，AL-12B和AL-5）的合成。

  An effective multi-step continuous flow approach towards N-diaminoalkylated 3-arylmethylene-2,3-dihydro-1H-isoindolin-1-ones, including the local anesthetic compound AL-12, has been realized. Compared to the traditional decoupled batch processes, the combined photochemical–thermal–thermal flow setup rapidly provides the desired target compounds in superior yields and significantly shorter reaction
