✦ Synopsis

A number of N-(arylsulfonyl)bicyclo[2.2.1]hept-2-enendo-5-methylamines have been synthesized from bicyclo[2.2.1]hept-2-en-endo-5-carbonitrile via reduction of the latter by lithium aluminum hydride and subsequent reactions of the resulting amine with arylsufonyl chlorides. The structures and stereochemical homogeneity of the products have been supported by the analysis of 1 H NMR spectra and by COSY-experiments. The reactions of the sulfonamides with peroxyphthalic acid are accompanied by intramolecular cyclizations and are completed by the formation of N-(arylsulfonyl)-exo-2-hydroxy-4-azatricyclo[4.2.1.0 3,7 ]nonanes. The structures of the substituted azabrendanes have been confirmed by spectral methods. The molecular structure of N-(p-methoxycarbonylaminophenylsulfonyl)-exo -2-hydroxy-4-azatricyclo[4.2.1.0 3,7

]nonane 8j has been determined by X-ray diffraction analysis.
