Abstract A facile and efficient synthesis of polysubstituted quinolin-2(1H)-ones is developed via intramolecular cyclization of readily available N-aryl cinnamides promoted by triflic anhydride in N,N-dimethyl trifluoroacetamide (DTA) under mild conditions. A facile and efficient synthesis of polysubstituted quinolin-2(1H)-ones is developed via intramolecular cyclization of readily available N-aryl
摘要 通过在温和的条件下在N,N-二甲基三氟乙酰胺(DTA)中由三氟甲磺酸酐促进的易于获得的N-芳基肉桂酸酯的分子内环化作用,开发了一种简便,有效的多取代喹啉2(1 H)-酮合成方法。 通过在温和的条件下在N,N-二甲基三氟乙酰胺(DTA)中由三氟甲磺酸酐促进的易于获得的N-芳基肉桂酸酯的分子内环化作用,开发了一种简便,有效的多取代喹啉2(1 H)-酮合成方法。
