  N-terminal strategy (N1–N4) toward high performance liquid crystal materials

  摘要：

  Liquid crystal materials have a variety of applications in many fields such as display techniques as well as photonics and optics. However, only few design principles have been disclosed on liquid crystal materials with different N-heterocycles as the terminal groups, which hinder the development of the heterocyclic liquid crystals. Here, a strategy of molecular design for N-heterocyclic liquid crystal materials is reported. On the basis of this strategy, a series of convenient N-heterocycles such as pyrrole, pyrazole, imidazole, 1,2,3-triazole, 1,2,4-triazole, 1,2,3,4-tetrazole were applied to synthesize the novel liquid crystals. Most of them have proved to exhibit good mesomorphic behaviors which make them excellent components in the mixture of the LCDs materials. The simple attachment of N-heterocyclic units to the liquid crystal molecules through a mild reaction condition will provide a good prospect for the design of N-heterocyclic liquid crystals.

  targets containing basic nitrogen groups that are prevalent in medicinally active agents. When combined with organozinc-mediated C–C bond formation, our protocol enabled the direct methylation of a myriad of amine derivatives including those that have previously been explored for the “magic methyl” effect. This synthesis strategy thus circumvents multistep de novo synthesis that is currently necessary to

  “神奇的甲基”效应，通过掺入单个甲基来显着提高生物活性化合物的效力，为药物化学家在药物发现过程中采用的简单而强大的策略提供了一种简单而强大的策略。尽管取得了重大进展，但能够对结构复杂的药物进行选择性 C(sp 3 )–H 甲基化的方法仍然非常有限。在这项工作中，我们公开了一种通过电化学氧化对受保护胺（即酰胺、氨基甲酸酯和磺酰胺）进行α-甲基化的模块化、高效和选择性策略。机理分析指导我们在经典的Shono氧化反应的基础上开发了一种改进的电化学方案，该反应具有反应范围广、官能团兼容性高、操作简单等特点。重要的是，该反应系统适合于药物活性剂中常见的含有碱性氮基团的复杂靶标的后期功能化。当与有机锌介导的 C-C 键形成相结合时，我们的方案能够实现多种胺衍生物的直接甲基化，包括那些先前已探索过的“神奇甲基”效应。因此，这种合成策略规避了目前获得此类化合物所必需的多步骤从头合成，并且有可能加速药物发现工作。
