英文摘要：

The compound C26H28N2O7 has been synthesized by the 1,3-dipolar reaction of N-benzyl isatin,amino-ester and methyl acrylate in toluene under stirring at room temperature catalyzed by racemic phosphoric acid,and achieved the construction of multi-functional spirooxindole-based tetrahydropyrroles skeleton.The structure was determined by single crystal X-ray diffraction.The crystal is triclinic,space group is P-1,with Mr=480.50,a = 0.895 73（3）nm,b = 0.956 10（2）nm,c=1.503 61（3）nm,V = 1.252 31（6）nm3,Z = 2,Dc= 1.274g/mm3,μ= 0.771mm-1,F（000）=508.The structure was solved by direct methods and refined by full-mat rix least squares method to the get final R=0.070 7,ωR =0.139 9.X-ray analysis reveals that the newly formed ring of tetrahydropyrrole in the crystal structure is envelope conformation,and it is similar vertical with indole ring.
