to the synthesis of highly functionalized 3-unsubstituted 2-aroylindoles is described. Moderate to good yields were obtained through the reaction of easily accessible N-(2-formylphenyl)trifluoroacetamides and α-bromoacetophenones in the presence of K2CO3. PEG-400 was found to be an efficient and reusable solvent in the process. 2-aroylindoles - PEG-400 - N-(2-formylphenyl)trifluoroacetamides - heterocycles
描述了一种一锅法且对环境无害的方法,用于合成高度官能化的3-未取代的2-芳酰基吲哚。在K 2 CO 3存在下,通过容易获得的N-(2-甲酰基苯基)三氟乙酰胺与α-溴乙酰苯的反应,可得到中等至良好的收率。发现PEG-400是该过程中有效且可重复使用的溶剂。 2-芳基吲哚-PEG-400- N-(2-甲酰基苯基)三氟乙酰胺-杂环-环化
