Synthesis of 1,4,7,7-tetramethylbicyclo[2.2.1]hept-exo-2-ylacylamines

A procedure has been developed for the selective preparation of 2-methylisoborneol by the action of methyllithium on camphane. It has been shown that the interaction of 2-methylisoborneol with aceto- and benzonitriles in the presence of sulfuric acid gives, as the result of a rearrangement of the carbon skeleton, high yields of the corresponding 1,4,7,7-tetramethylbicyclo[2.2.1]hept-exo-2-ylacylamines, which possess an anticataleptic action.Institute of Physical Organic Chemistry, Belarus Academy of Sciences, Minsk.
