Synthesis and reactivity of amines containing several cage-like fragments

By reaction of bicyclo[2.2.1]hept-5-en-exo- and endo-2-ylmethylamine, exo-5,6-epoxybicyclo[2.2. 1]hept-exo-2-ylmethylamine and benzylamine with 1-adamantanecarbonyl chloride, 1,3-adamantanedicarbonyl dichloride, and 1,3-adamantanediacetyl dichloride amides were obtained with one, two, and three cage-like fragments that were reduced to amines by lithium aluminum hydride. The reactivity of the amines was evaluated with the use of semiempirical quantum-chemical method PM3. Derivatives of the amines were prepared by reactions with arenesuffonyl chlorides, p-nitrobenzoyl chloride, succinic and endic anhydrides, p-toluenesulfonyl and m-tolyl isocyanates, phenyl isothiocyanate, and p-nitrophenyloxirane. The structure of the new compounds was supported by analysis of their IR and H-1 NMR spectra. The dependence of some reaction conditions was observed on the number and remoteness of the cage-like fragments from the reaction centers of the amines.
