| Abstract: | The 1,3_dipolar cycloaddition reactions between N_methyl(or benzyl)_3_hydroxypyridium halides and election_deficient dipolar_philes, such as methyl vinyl ketone, acrylonitrile, methyl acrylate were studied. The reaction conditions were investigated. The configuration and exo/endo ratios of the cycloaddition products were reported. |
