1,3-Dipolar cycloaddition to Cyo of an azomethine ylide,which was generated in situ from refluxing a mixture of cyclohexanone and DL-valine in chlorobenzene under N2 afforded a monoadduct and a bisadduct.Even for longer reaction time,however,only monoadduct was obtained from the reaction of C70 with an azomethine ylide generated from refluxing a mixture of 2-undecanone and 2-aminoisobutyric acid in chlorobenzene under N2 The electrochemical properties of all the products were studied by cyclic voltammetry. 1,3-Dipolar cycloaddition to Cyo of an azomethine ylide, which was generated in situ from refluxing a mixture of cyclohexanone and DL-valine in chlorobenzene under N2 afforded a monoadduct and a bisadduct.
