A series of 1-aryl-1,2-dihydrobenzo[f]quinolin-3(4H)-one derivatives and 4-aryl-7,7-dimethyl-5-oxo-3,4,5,6,7,8-hexahydrocoumarin derivatives have been synthesized by one-pot multicomponent reaction of Meldrum’s acid with benzaldehyde, naphthalene-2-amine, or cyclohexanedione in PEG-400. The method has the advantages of mild reaction conditions, good yields, and easy processing, and is environmentally
一系列1-芳基-1,2-二氢苯并[ f ]喹啉-3(4 H)-一衍生物和4-芳基-7,7-二甲基-5-氧代-3,4,5,6,7,通过Meldrum的酸与苯甲醛,萘-2-胺或环己二酮在PEG-400中的一锅多组分反应合成了8-六氢香豆素衍生物。该方法的优点是反应条件温和,收率好,易加工,对环境无害。
