The regioselective three-component condensation of azomethine ylides derived from isatins and α-amino acids with acrylamides or aroylacrylic acids as dipolarophiles has been realized through a one-pot 1,3-dipolar cycloaddition protocol. Decarboxylation of 2'-aroyl-2-oxo-1,1',2,2',5',6',7',7a'-octahydrospiro[indole-3,3'-pyrrolizine]-1'-carboxylic acids is accompanied by cyclative rearrangement with formation of dihydropyrrolizinyl indolones.
通过一锅 1,3-偶极环加成反应，实现了靛红亚胺叶立德与α-氨基酸、丙烯酰胺或芳基丙烯酸的区域选择性三组分缩合反应。2'-芳基-2-氧代-1,1',2,2',5',6',7',7a'-八氢螺[吲哚-3,3'-吡咯嗪]-1'-羧酸发生脱羧反应，同时伴随着环化重排，生成二氢吡咯并[吲哚]酮。
