A methodology for the synthesis of α- and β-carbolines from fluoropyridines and 2-haloanilines is reported. This procedure consists of a four-step directed ortho-lithiation, zincation, Negishi cross-coupling, and intramolecular nucleophilic aromatic substitution, providing access to a diverse set of functionalized carbolines. While the procedure is applicable to batch conditions, the generation of
报道了一种从氟吡啶和 2-卤代苯胺合成 α-和 β-咔啉的方法。该过程包括四步定向邻位锂化、锌化、Negishi 交叉偶联和分子内亲核芳族取代,提供了获得多种功能化咔啉的途径。虽然该程序适用于分批条件,但已经证明了在连续流动中生成芳基锌中间体。
