A series of new β‐lactam derivatives 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k, 4l were synthesized from [2 + 2] cycloaddition reaction of imines containing quinoline moiety 3a, 3b, 3c, 3d, 3e, 3f with ketene generated in situ from chloroacetyl chloride in dry Et3N. The structures of the prepared compounds were characterized by IR, MS, 1H NMR, and elemental analysis. In addition, the structure of
一系列新的β内酰胺衍生物4A,4B,4C,4D,4E,4F,4克,4H,4I,4J,4K,4升从合成[2 + 2]的含喹啉部分亚胺的环加成反应图3a,3b中,3c,3d,3e,3f,其中氯乙酰氯在干燥的Et 3 N中原位生成乙烯酮。制备的化合物的结构用IR,MS,1表征1 H NMR和元素分析。此外,(4i)的结构是通过单晶X射线晶体学确定的。
