Chlorination, bromination, and condensation reactions of 3-(1-ethy1-4-hydroxy-2-oxo-1,2-dihydroquinolin-3-yl)-3-oxopropanoic acid (3) were studied. Some novel 4-hydroxyquinolin-2(1H)-ones and pyrano[3,2-c]quinolin-2(1H)-ones were also prepared. The structures of the novel compounds were established by elemental analyses and spectral data. All the products were also screened in vitro for their antimicrobial activity.
研究了 3-(1-乙基 1-4-羟基-2-氧代-1,2-二氢喹啉-3-基)-3-氧代丙酸 (3) 的氯化、溴化和缩合反应。 还制备了一些新型 4-羟基喹啉-2(1H)-酮和吡喃并[3,2-c]喹啉-2(1H)-酮。 通过元素分析和光谱数据确定了这些新型化合物的结构。 还对所有产品进行了体外抗菌活性筛选。
