catalyzed synthesis of chalcogenated N‐aryl‐7‐azaindoles/azaindolines has been developed through N‐directed ortho Csp2−H activation in presence of silver triflate and silver carbonate in 1,4‐dioxane using dichalcogenides. We have established this methodology as being efficient, highly regioselective and scalable, having a broad substrates scope. Through this route, a range of substrates have furnished
在三氟甲磺酸银和碳酸银在1,4-二恶烷中使用二硫化氢,在N-定向的邻位C sp 2 -H活化下,铑催化合成硫属N-芳基-7-氮杂吲哚/氮杂二吲哚。我们已经建立了一种高效,高度区域选择性和可扩展性的方法,具有广泛的底物范围。通过这种途径,许多底物以良好或优异的产率提供了氮杂吲哚和氮杂吲哚啉的硫醇化和硒基化。这些分子在生物和/或材料科学中可能具有潜在的应用。
