synthesized with domino ring closure. A click reaction was performed to create the 1,2,3-triazole heterocyclic ring, followed by an RDA reaction resulting in dihydropyrimido[2,1-a]isoindole-2,6-diones. The absolute configuration, concluded by the norbornene structure that served as a chiral source, remained constant throughout the transformations. The structure of the synthesized compounds was examined by
已经开发出一种简单、高产的合成路线来构成复杂的杂环,应用多米诺骨牌、点击和逆狄尔斯-阿尔德 (RDA) 反应序列。从 2-氨基甲酰胺开始,合成了一组具有多米诺环闭合的新异吲哚并[2,1-a]喹唑啉酮。进行点击反应以产生 1,2,3-三唑杂环,然后进行 RDA 反应,产生二氢嘧啶并 [2,1-a] 异吲哚-2,6-二酮。由作为手性来源的降冰片烯结构得出的绝对构型在整个转化过程中保持不变。通过 1H 和 13C 核磁共振 (NMR) 方法检查合成化合物的结构。
