  摘要：

  在这里，我们报告了一种反应，该反应通过将芳基羰基阳离子等价物分别插入吡咯和吲哚核心选择性地产生 3-芳基吡啶和喹啉基序。通过使用 α-chlorodiazirines 作为相应氯卡宾的热前体，可以修改作为母体 Ciamician-Denstedt 重排核心的传统基于卤仿的协议，以直接提供 3-（杂）芳基吡啶和喹啉。通过氧化可商购的脒鎓盐可方便地在一个步骤中制备氯二氮嗪。检测了作为吡咯取代模式函数的选择性，并提出了基于空间效应的预测模型，DFT 计算支持确定选择性的环丙烷化步骤。计算出人意料地表明，环丙烷化的立体化学对随后形成吡啶核心的电环开环几乎没有影响，这是由于补偿性同芳族稳定化抵消了轨道控制的扭矩选择性效应。通过喹啉的制备和药学相关吡咯的骨架编辑进一步证明了这种骨架转化的效用。

  ortho-position to the pyrimidyl core. The structure–activity relationship for the rest of the molecule in this 2-heteroarylpyrimidine series mimics that of the [1,2,4]triazolo[1,5-a]pyrimidine series. Like triazolopyrimidines and 2-cyanoaminopyrimidines, the 2-heteroarylpyrimidines retain the capability to overcome multidrug resistance due to Pgp. Mechanism of action studies showed that the lead compounds behaved

  A series of compounds structurally related to bosentan 1 featuring an unsaturated side chain at position 6 of the core pyrimidine have been studied for their potential to block the ET(A) and ET(B) receptor. Incorporation of a 2-butyne-1,4-diol linker bearing a pyridyl carbamoyl moiety led to in vitro highly potent endothelin receptor antagonists (e.g., 70 and 75).
