Treatment of pyridine and dimethyl acetylenedicarboxylate derivatives with N-substituted isatylidene derivatives resulted in three-component condensations, affording 1′,9a′-dihydrospiro[indoline-3,2-quinolizin]-2-one derivatives in high yields and with good diastereoselectivities through 1,4-dipolar cycloadditions.
用 N-取代的异亚甲基衍生物处理吡啶和二甲基乙炔二羧酸衍生物导致三组分缩合,得到 1',9a'-二氢螺[indoline-3,2-quinolizin]-2-one 衍生物,通过1,4-偶极环加成。
