An efficient KI/TBHP-promoted [3 + 2] cycloaddition of pyrrolo[1,2-a]quinoxalines and N-tosylhydrazones is described. A series of diverse fused [1,2,4]triazolo[3,4-c]quinoxalines was obtained in moderate to good yields with wide functional group tolerance. Importantly, this reaction can be performed on a gram scale, even in a one-pot fashion. In addition, further transformations of the products were
描述了高效的KI / TBHP促进的吡咯并[1,2-a]喹喔啉和N-甲苯磺酰hydr的[3 + 2]环加成。以中等至良好的收率获得了一系列不同的稠合[1,2,4]三唑并[3,4-c]喹喔啉,并具有宽泛的官能团耐受性。重要的是,即使以一锅法,该反应也可以以克为单位进行。另外,还研究了产物的进一步转化。
