A pseudo-five-component reaction involving double decarboxylative 1,3-dipolar cycloaddition of azomethine ylides with olefinic oxindoles for the diastereoselective synthesis of bispiro[oxindole-pyrrolidine]s is developed. The major diastereomers are unique butterfly shaped compounds with a plane of symmetry. Recyclable zeolite HY acid catalyst is used to promote the reaction, and only CO and HO are generated as byproducts.
开发了一种涉及甲亚胺叶立德与烯基氧化吲哚的双脱羧1,3-偶极环加成反应的伪五组分反应,用于非对映选择性合成双螺[氧化吲哚-吡咯烷]。主要非对映异构体是具有对称平面的独特蝴蝶形化合物。使用可回收的HY沸石酸催化剂促进反应,仅生成CO和HO作为副产物。
