含氮杂环在药物和类药物化合物中无处不在;然而,区域选择性合成已被证明具有挑战性。在此,我们报告了我们为开发合成吡唑并[1,5- a ]吡啶的区域选择性方法所做的努力,并偶然发现了一种用于区域选择性形成咪唑并[1,5- a ]吡啶的方案。总之,这些转化允许从一个共同的中间体快速和选择性地形成两个重要的杂环基序。

A series of tricyclic pyridones has been evaluated as benzodiazepine site ligands with functional selectivity for the alpha(3) over the alpha(1) containing subtype of the human GABA(A) receptor ion channel. This investigation led to the identification of a high affinity, functionally selective, orally bioavailable benzodiazepine site ligand that demonstrated activity in rodent anxiolysis models and reduced sedation relative to diazepam.
