摘　　要：A convenient,economical and green approach to the synthesis of 1H-indazolo[1,2-b]phthalazine-1,6,11-trione derivatives has been achieved via a one-pot protocol using phthalhydrazide,a cyclic-β-diketone and an aldehyde in the presence of a ceric ammonium nitrate catalyst in polyethylene glycol.The simple work up,mild conditions,excellent yields,inexpensive and non-toxic catalyst and simple solvent recyclability render this protocol both attractive and economically viable. 关键词：催化合成协议生态友好 CAN 邻苯二甲酰合成方法酮衍生物聚乙二醇
