An efficient Pd-catalyzed direct C-H arylation of pyrrolo[1,2-]quinoxalines with aryl iodides is described, providing a selective route toward a series of 1-arylated and 1,3-diarylated pyrrolo[1,2-]quinoxalines in good yields. This method features a broad substrate scope, good functional group tolerance and gram-scale synthesis. Furthermore, the C3-thiocyanation of the arylated product is also achieved. We believe that these novel aryl-substituted pyrrolo [1,2-]quinoxalines will have a variety of applications in organic synthesis and medicinal chemistry.
一种高效的 Pd 催化的吡咯并[1,2-]喹喔啉与芳基碘化物的直接 C-H 芳基化反应被描述，为一系列 1-芳基和 1,3-二芳基吡咯并[1,2-]喹喔啉的合成提供了一条选择性途径，产率良好。该方法具有广泛的底物范围、良好的官能团耐受性和克级规模的合成。此外，还实现了芳基化产物的 C3-硫氰化反应。我们相信这些新型的芳基取代的吡咯并[1,2-]喹喔啉将在有机合成和药物化学中有多种应用。
