Abstract
Mannich condensation of exo-2,exo-6-tricyclo[5.2.1.02,6]decan-8-one with paraformaldehyde and dimethylamine hydrochloride results in the addition of dimethylaminomethyl fragment at the C9 atom to give the exo-9-isomer. The reaction of exo-9-dimethylaminomethyl-exo-2,exo-6-tricyclo[5.2.1.02,6]decan-8-one with hydroxylamine hydrochloride in alcoholic alkali yields the corresponding Z-oxime which undergoes selective rearrangement into exo-10-dimethylaminomethyl-9-aza-exo-2,exo-6-tricyclo[5.3.1.02,6]undecan-8-one by the action of sulfuric acid in acetonitrile.
