We report an iodine-catalyzed Povarov reaction using indole as dienophile carried out in toluene at room temperature. This three-component reaction, coupling an aldehyde, an amine, and an indole, proved to be an efficient method for synthesizing exo-indolo[3,2-c]quinoline derivatives related to the alkaloid isocryptolepine (cryptosanguinolentine) in good yield and with high stereoselectivity.
我们报告了使用吲哚作为亲二烯体在室温下在甲苯中进行的碘催化的 Povarov 反应。这种将醛、胺和吲哚偶联的三组分反应被证明是一种以良好收率合成与生物碱异隐碱(cryptosanguinolentine)相关的外型吲哚并[3,2-c]喹啉衍生物的有效方法。高立体选择性。
