developed a modular and flexible approach for the synthesis of teraryl‐based α‐helix mimetics. Central to our strategy is the use of a benzene core unit featuring two leaving groups of differentiated reactivity in the Pd‐catalyzed cross‐coupling used for terphenyl assembly. With the halogen/diazonium route and the halogen/triflate route, two strategies have successfully been established. The synthesis of core
基于Teraryl的α-螺旋模拟物已被证明是抑制蛋白质-蛋白质相互作用(PPI)的有用化合物。我们开发了一种模块化且灵活的方法来合成基于芳基的α-螺旋模拟物。我们策略的核心是使用苯核心单元,该核心单元在用于三联苯组装的Pd催化交叉偶联中具有两个不同反应性的离去基团。通过卤素/重氮途径和卤素/三氟甲磺酸途径,已经成功建立了两种策略。报道了具有脂肪族(Ala,Val,Leu,Ile),芳香族(Phe),极性(Cys,Lys),亲水性(Ser,Gln)和酸性(Glu)氨基酸侧链的核心结构单元的合成。
