We have developed a highly efficient synthetic route to carbazoles that employs sequential C–C/C–N bond formation via Suzuki cross-coupling and Cadogan cyclization. The developed method is compatible with electron neutral, rich or deficient substrates. The synthetic utility of this method was demonstrated by the concise syntheses of four natural products.
我们已经开发出一种高效的合成路线,用于合成咔唑,该路线利用了顺序C–C/C–N键形成,通过Suzuki交叉偶联和Cadogan环化。这种方法适用于电子中性、富电子或缺电子底物。通过这种方法的简洁合成,我们展示了四种天然产物的合成效用。
