A series of novel spiropyrrolidine derivatives were synthesised via three-component 1,3-dipolar cycloaddition reactions of 1-(1-methylpyrrole-2-yl)-3-aryl-2-cyano-1-propenones, isatin and sarcosine in refluxing methanol. The method affords a fast one-pot synthesis of spiroheterocycles in high yields. Their structures were established by 1H NMR, IR and elementary analysis.
通过1-(1-甲基吡咯-2-基)-3-芳基-2-氰基-1-丙烯酮、靛红和肌氨酸在回流甲醇中的三组分1,3-偶极环加成反应合成了一系列新型螺吡咯烷衍生物. 该方法提供了高产率的螺杂环的快速一锅合成。它们的结构通过1H NMR、IR和元素分析确定。
