New spiro[indeno[1,2‐b]quinoxaline‐11,2′‐pyrrolidine] derivatives were prepared in high yield stereoselectively from an efficient multicomponent 1,3‐dipolar cycloaddition reaction between ninhydrin, phenylenediamine, sarcosine, and chalcones. The regiochemistry and stereochemistry of resultant cycloadducts have been determined by several 2D NMR spectroscopic techniques and X‐ray single crystal diffraction
通过茚三酮,苯二胺,肌氨酸和查耳酮之间有效的多组分1,3-偶极环加成反应,高选择性地立体选择性地制备了新的螺[茚并[1,2-b]喹喔啉-11,2'-吡咯烷]衍生物。已通过几种2D NMR光谱技术和X射线单晶衍射确定了所得环加合物的区域化学和立体化学。J.杂环化学。(2012)。
