ABSTRACT A facile regio and stereoselective synthesis of novel spiro[indolin-3,2′-pyrrolidin]-2-one’s have been accomplished through 1,3-dipolar cycloaddition of azomethine ylides generated in situ from the reaction of isatin and benzyl amine with quinoline bearing dipolarophiles in good yields. The synthesized compounds were well characterized through different spectroscopic techniques, such as single
摘要 通过靛红和苄胺与喹啉反应原位生成的偶氮甲碱叶立德的 1,3-偶极环加成反应,实现了新型螺[indolin-3,2'-pyrrolidin]-2-one's的简便区域和立体选择性合成以良好的产率携带偶极体。通过不同的光谱技术,如单晶 XRD、FTIR、NMR 和质谱分析,对合成的化合物进行了很好的表征。图形概要
