A series of substituted 5-, 6-, and 7-azaindoles were prepared via the Hemetsberger-Knittel reaction. In general, better yields were obtained at higher temperatures and shorter reaction times than required for the formation of the analogous indoles, and in some cases, only decomposition occurred below a minimum temperature. The resulting templates offer up to five sites for subsequent functionalization
通过 Hemetsberger-Knittel 反应制备了一系列取代的 5-、6-和 7-氮杂吲哚。一般来说,在更高的温度和更短的反应时间下获得比形成类似吲哚所需的更好的产率,并且在某些情况下,仅在最低温度以下发生分解。生成的模板为后续功能化提供多达五个位点,以实现广泛的化学多样性。
