Dipolar Cycloaddition Reactions of Isatin Derived Azomethine Ylide with 3,4-Diphenylcyclobutene-1,2-dione: Synthesis of Novel Spiro[oxindole-3,2′-pyrrolidine] Derivatives

Dipolar Cycloaddition Reactions of Isatin Derived Azomethine Ylide with 3,4-Diphenylcyclobutene-1,2-dione: Synthesis of Novel Spiro[oxindole-3,2′-pyrrolidine] Derivatives

Azomethine ylide, generated by the decarboxylative condensation of sarcosine with isatins has been trapped by 3,4-diphenylcyclobutene-1,2-dione to afford novel spiro[oxindole-3,2′-pyrrolidine] derivatives.
