  catalysis protocol for the synthesis of 4-(pyridin-2-ylmethyl)-2-aminopyrroles (PMAPs) was constructed by simply refluxing a mixture of ethyl 2-(pyridin-2-yl)acetates 1 and various types of arylglyoxal monohydrates 2 and different heterocyclic ketene aminals 3 in EtOH solvent. Based on this reaction, a series of highly functionalized PMAPs were obtained through a novel cascade reaction accompanied by a decarboxylation

  通过简单地回流2-（吡啶-2-基）乙酸乙酯乙基1和各种类型的芳基乙二醛的混合物，构建了用于合成4-（吡啶-2-基甲基）-2-氨基吡咯（PMAP）的多组分束缚催化方案。一水合物2和不同的杂环烯酮缩醛3在EtOH溶剂中。基于该反应，通过伴随脱羧机理的新型级联反应获得了一系列高度官能化的PMAP。结果，将吡啶-2-基甲基成功地引入了目标化合物中，并且使用本研究中描述的级联反应可以轻松构建PMAPs库。该方案表明，最重要的特征是2-（吡啶-2-基）乙酸酯的脱羧反应1，它可以在吡啶-2-基甲基-取代的杂环，包括吡咯类，吡啶类，喹诺酮类，以及类似于那些在自然界中发现的其它杂环化合物的合成中使用。

  This study is based on our attempts to further explore the structure-activity relationship (SAR) of VX-148 (3) in an attempt to identify inosine 5'-mono-phosphate dehydrogenase (IMPDH) inhibitors superior to mycophenolic acid. A five-point pharmacophore developed using structurally diverse, known IMPDH inhibitors guided further design of novel analogs of 3. Several conventional as well as novel medicinal chemistry strategies were tried. The combined structure-and ligand-based approaches culminated in a few analogs with either retained or slightly higher potency. The compounds which retained the potency were also checked for their ability to inhibit human peripheral blood mononuclear cells proliferation. This study illuminates the stringent structural requirements and strict SAR for IMPDH II inhibition.
