摘要
以芳香醛、海因为原料,水为溶剂,经Knoevenagel缩合反应制得5-芳亚甲基海因后,再在室温超声波辐射下与靛红和L-脯氨酸发生1,3-二极环加成一锅反应,得到一系列双螺环化合物,收率为78%~94%.对产物结构进行红外、核磁及质谱表征.
Series of dispirooxindole derivatives were synthesized in one-step from aromatic alde- hydes and hydantoin by Knoevenagel condensation to afford 5-arylideneimidazolidine-2, 4-diones, which were subjected to 1, 3-dipoiar cyclo-addition with isatin and L-proline under ultrasonic irra- diation with yields of 78%--94%. The structure of the products were confirmed by infrared, nu- clear magnetic resonance and mass spectrometry.
