New routes for the synthesis of aminoquinolizinone derivatives with interesting biological activities are reported. Reactions enaminones 2 and 9 with malononitrile affords aminoquinolizinone derivatives 7a and 7b. Fusion of acetylcyclohexanone (1) with DMF DMA and ethyl cyanoacetate affords only product 11. Treatment of the latter product with malononitrile affords the aminoquinolizinone derivative
报道了合成具有有趣生物活性的氨基喹嗪酮衍生物的新途径。烯胺2和9与丙二腈的反应得到氨基喹嗪酮衍生物7a和7b。乙酰基环己酮(1)与DMF DMA和氰基乙酸乙酯的融合仅提供产物11。用丙二腈处理后一产物得到氨基喹啉酮衍生物15。查耳酮17与丙二腈的反应提供了产物22。(1)与亚芳基丙二腈23a,b的缩合分别提供化合物28a,b。通过元素分析和1 H NMR光谱,以及在某些情况下通过13 C NMR研究,阐明了新合成化合物的结构。
