Abstract A convenient three‐step route toward a functionalized pyrrole building block for novel anti‐inflammatory agents is reported. In contrast to previous strategies, the present approach focuses on inexpensive starting materials and application on a multigram scale. A high degree of functional diversity is demonstrated in various derivatives, and the scope and limitations of this route are discussed
摘要 报道了一种用于新型抗炎剂的功能化吡咯构建块的便捷三步路线。与以前的策略相比,本方法侧重于廉价的起始材料和多克规模的应用。各种衍生物表现出高度的功能多样性,并讨论了该途径的范围和局限性。与所描述的四取代吡咯互补,一种基于 Feist-Benary 缩合的新型闭环方案提供了三取代的类似物。
