by-product, 2-phenylpyrrolo [1,2-a] quinoline, is isolated and characterized during the preparation of bioactive Pyridinium and quinolinium salts at ambient temperature. This protocol turned out to be an efficient approach for the one-pot synthesis of a series of 2-phenylpyrrolo [1,2-a] quinoline derivatives from 2-methyl quinoline and substituted phenacyl bromides. This method implicates a transition
在环境温度下制备生物活性吡啶鎓盐和喹啉鎓盐的过程中,分离并表征了一种关键的副产物 2-苯基吡咯并 [1,2- a ] 喹啉。该方案被证明是一种有效的方法,用于从 2-甲基喹啉和取代的苯甲酰溴一锅合成一系列 2-苯基吡咯并 [1,2- a ] 喹啉衍生物。该方法涉及过渡金属基催化剂和无碱、环境友好的无溶剂反应条件。所有新合成的衍生物均已通过1 H-NMR、13 C-NMR 和 HRMS 进行了表征。
