通过N-甲苯磺酰hydr和硼酸之间的多米诺环化反应,合成了具有全碳四元桥头中心的多环分子。通过环过环杂环化反应,一般级联反应的变体已被用于制备3-奎宁环酮和相关的生物碱样支架。此外,使用3-氰基丙基和4-氰基丁基硼酸以及α,β-不饱和N-甲苯磺酰基hydr酮通过史无前例的正式[ n +1]环化反应,包括了Hajos-Parrish酮的立体选择性螺环化反应,形成了螺环。所描述的所有新反应的共同特征是通过形成两个Csp 3来创建全碳四元中心-C键合在肼基碳原子上。基于DFT的计算表明发生了级联过程,其中涉及重氮化合物碳羰基化,然后在中间烯丙基硼酸上进行1,3-硼酸重排,并形成新颖的硼氮杂-氮烯环化反应。

We previously identified a spiro[piperidine-4,1-pyrido[3,4-b]indole] class of co-potentiators that function in synergy with existing CFTR potentiators such as VX-770 or GLGP1837 to restore channel activity of a defined subset of minimal function cystic fibrosis transmembrane conductance regulator (CFTR) mutants. Here, structure-activity studies were conducted to improve their potency over the previously
