A number of symmetric and unsymmetric endo-cis-dicarboxamides of the norbornene series containing dimethyl- and diethylamine, morpholine, perhydroazepine, and p-bromoaniline fragments were synthesized starting from endic anhydride with the aid of N,N'-dicyclohexylcarbodiimide. Oxidation of these amides with organic peroxy acids according to Prilezhaev gave exo-2-hydroxy-5-oxo-4-oxatricyclo[4.2.1.0(3,7)]-nonane-endo-9-carboxylic acid salts. The structure of the obtained products was confirmed by IR and H-1 NMR spectroscopy.
