  新型杂环磺酰胺γ-分泌酶抑制剂的合成及其构效关系

  摘要：

  业已证明，γ-分泌酶抑制剂可减少β-淀粉样蛋白的产生，β-淀粉样蛋白是在阿尔茨海默氏病患者的大脑中发现的斑块的一种成分。据报道，一系列新的杂环磺酰胺γ-分泌酶抑制剂可降低细胞中的β-淀粉样蛋白水平。与Notch（一种替代的γ-分泌酶底物）相比，该系列化合物的几个实例显示出更高的抑制淀粉样蛋白前体蛋白加工的倾向。

• Taming Ambident Triazole Anions: Regioselective Ion Pairing Catalyzes Direct N-Alkylation with Atypical Regioselectivity
  作者：Harvey J. A. Dale、George R. Hodges、Guy C. Lloyd-Jones

  of an organocatalytic methodology for ambident control in the direct N-alkylation of unsubstituted triazole anions. Amidinium and guanidinium receptors are shown to act as strongly coordinating phase-transfer organocatalysts, shuttling triazolate anions into solution. The intimate ion pairs formed in solution retain the reactivity of liberated triazole anions but, by virtue of highly regioselective

  控制环境亲核试剂对烷化剂的区域选择性是杂环化学中的一个基本问题。未取代的三唑特别具有挑战性，通常需要低效的逐步保护-去保护策略和预功能化方案。在此，我们报告了原型双基 1,2,4-三唑、1,2,3-三唑及其阴离子的烷基化，通过原位 1H/19F NMR、动力学模型、扩散有序 NMR 光谱、X 射线分析晶体学、高度相关的耦合簇计算 [CCSD(T)-F12、DF-LCCSD(T)-F12、DLPNO-CCSD(T)] 和 Marcus 理论。由此产生的机理见解允许设计一种有机催化方法，用于在未取代的三唑阴离子的直接 N-烷基化中进行环境控制。脒和胍受体显示出作为强协调相转移有机催化剂的作用，将三唑根阴离子穿梭到溶液中。在溶液中形成的紧密离子对保留了释放的三唑阴离子的反应性，但由于高度区域选择性的离子对，显示出完全反转（1,2,4-三唑）或显着增强（1,2,3-三唑）与母体阴离子相比。该方法允许一步直接获得
