- Abstract
Reactions of bicyclo[2.2.1]hept-5-ene- endo-2, endo-3-dicarboxanhydride (endic anhydride) with 2-, 3-, and 4-aminopyridines, 3-hydroxy- and 5-iodo-2-aminopyridines, 6-aminoquinoline, and 6-aminoquinoxaline involve chemoselective transformation of the exocyclic amino group. The resulting amido acids were converted into the corresponding carboximides, and the latter were epoxidated with peroxy acids. The structure of the products was confirmed by the IR, UV, and 1H and 13C NMR spectra, as well as by calculation of the 1H and 13C chemical shifts using the GIAO method (B3LYP/6-31G** approximation).
