  Optimization of 1,3,4-Benzotriazepine-Based CCK₂ Antagonists to Obtain Potent, Orally Active Inhibitors of Gastrin-Mediated Gastric Acid Secretion

  摘要：

  Starting from a novel, achiral 1,3,4-benzotriazepine-based CCK2 receptor antagonist, a process of optimization has afforded further compounds of this type that maintain the nanomolar affinity for recombinant, human CCK2 receptors and high selectivity over CCK1 receptors observed in the initial lead but display more potent inhibition of pentagastrin-stimulated gastric acid secretion in vivo. Moreover, this has largely been achieved without altering their potency at wild-type canine and rat receptors, as judged by their displacement of [I-125]-BH-CCK-8S in a radioligand binding assay and by their activity in an isolated, perfused rat stomach bioassay, respectively. 2-(5-Cyclohexyl-1-(2-cyclopentyl-2-oxo-ethyl)-2-oxo-1,2-dihydro-3H-1,3,4-benzotriazepin-3-yl)-N-(3-(5-oxo-2,5-dihydro- [1,2,4]oxadiazol-3-yl)-phenyl)-acetamide (47) was identified as the most effective compound stemming from this approach, proving to be a potent inhibitor of pentagastrin-stimulated gastric acid secretion in rats and dogs by intravenous bolus as well as by enteral administration.

• Complementary site-selectivity in arene functionalization enabled by overcoming the ortho constraint in palladium/norbornene catalysis
  作者：Jianchun Wang、Renhe Li、Zhe Dong、Peng Liu、Guangbin Dong

  site-selectivity in arene functionalization that is complementary to the site-selectivity from electrophilic aromatic substitution reactions has been a long-standing quest in organic synthesis. Palladium/norbornene cooperative catalysis potentially offers a unique approach to this problem, but its use has been hampered by the ortho constraint, which is the requirement of an ortho substituent for mono ortho functionalization

  在芳烃官能化中实现与来自亲电芳族取代反应的位点选择性互补的位点选择性一直是有机合成中的长期追求。钯/降冰片烯协同催化潜在地提供了解决该问题的独特方法，但是其使用受到邻位约束的阻碍，邻位约束是卤代芳烃单邻位官能化的邻位取代基的要求。在这里，我们表明可以使用新型的桥头修饰的降冰片烯类解决这一挑战，从而为具有互补位点选择性的芳烃功能化提供广泛有用的策略。一系列邻位以前有问题的底物未取代的芳基碘化物现在可以用来有效地提供单邻位官能化的产物。该方法适用于复杂生物活性分子在常规方法难以达到的位置的后期功能化。

  in organic synthesis. Herein, a hybrid heterogeneous catalyst, palladium(0) on copper ferrite nanowires, has been synthesized, characterized, and for the first time, employed in the Jeffrey Heck reaction between iodoarenes and allylic alcohols, and good to excellent yields have been obtained. In addition, the catalyst was found to be suitable for the usual Heck coupling. The nanocatalyst was recovered
