An efficient one-pot approach for the synthesis of quinolines from -aminothiophenol and 1,3-ynone under mild conditions is disclosed. With the aid of ESI-MS analysis and parallel experiments, a three-step mechanism is proposed-a two-step Michael addition-cyclization condensation step leading to intermediate 1,5-benzothiazepine catalyzed by zirconocene amino acid complex CpZr(η-CHNO), followed by I-mediated desulfurative step.
公开了一种在温和条件下由β-氨基苯硫酚和1,3-烯炔酮高效一锅法合成喹啉的方法。借助电喷雾电离质谱（ESI-MS）分析和平行实验，提出了一种三步机理——由二茂锆氨基酸络合物CpZr(η⁵-CHNO)催化的两步迈克尔加成-环化缩合步骤，生成中间体1,5-苯并硫氮杂䓬，随后是碘介导的脱硫步骤。
