the efficient synthesis of pyrrolo(indolo)[1,2-a]quinoxalines and pyrrolo(indolo)[3,2-c]-quinolines from readily available nitrobenzenes and glycols is reported. The process utilizes the carbonyl byproduct of the initial dioxomolybdenum(VI)-catalyzed reduction of nitroaromatics with glycols as a reagent for the imine generation. This method represents the first sustainable domino reaction for the preparation
一种新型的多米诺骨牌还原/亚胺形成/分子内环化/氧化反应,用于从容易获得的硝基苯和乙二醇中高效合成吡咯并[吲哚] [1,2-a]喹喔啉和吡咯并[吲哚] [3,2-c]喹啉报告。该方法利用最初的二氧钼(VI)催化的硝基芳族化合物的还原羰基副产物与乙二醇作为亚胺生成试剂。该方法代表了制备生物相关杂环的第一个可持续的多米诺反应,该反应将第一步中形成的废物内部掺入最终产品中。
