这是第一个描述设计,合成和掺入可有效形成5',5'-连接的交替链Hoogsteen三链体的插入式接头的报告。使用分子建模,以一种非常简单的方式解决了5',5'问题。两个相对较远的5'-末端已与一个分子连接,该分子为结构提供了刚性,同时又具有足够的柔韧性以允许在所有四根链上堆叠。Sonogashira进行了设计分子核心的合成适当取代的碘苯与1,3-二乙炔基苯偶合,得到共轭体系,其中三个苯环与三键互连。对于用插入连接子获得的交替链三链体,获得的稳定性高于具有相同总长度和相同核苷酸的相应同源三链体的稳定性。这是由交替三元组的熔化温度高5°得出的。交替链三链体对错配的敏感性与同三链体所观察到的范围相同(ΔT m = -13°至-19°)。
详细的实验和计算研究揭示了疏水相互作用在刚性小分子 DNA 杂化 (rSMDH) 构建块向纳米笼和面对面 (ff) 二聚体结构的水性组装中发挥的重要作用。在水性环境中,这些纳米结构中有机核心的疏水表面通过与另一个 rSMDH 中的核心、连接的 DNA 链中的碱基和/或最终组装结构中的碱基对相互作用而最小化。在组装过程中无法正确分离核心的疏水表面的情况下,即使在低浓度的 DNA 下,也会产生不明确的网络而不是二聚体。相比之下,如果可以形成 ff 二聚体,并且可以很好地减少核心的暴露疏水表面,
for the construction of n-membered (n>3) N-heterocycles, rely upon two chemical operations by involving sequential nucleophilic and electrophilic C-N bond formations. Here, we report a highly efficient cascade of alkyne insertion/C-H activation/amination for the rapid preparation of a myriad of tricyclic indoles, in a single-step transformation, by using bifunctional secondary hydroxylamines.
