Omega-dialkylaminoalkyl ethers of 3-exo-dialkylamino-(Z)-camphoroximes with antiarrhythmic and local anesthetic activities.

The synthesis of 3-exo-dialkylamino-(Z)-camphoroximes 7 starting from a mixture of 3-endo- and 3-exo-bromocamphornitrimine, hydroxylamine hydrochloride and excess secondary amine (dimethylamine, pyrrolidine, piperidine or morpholine) is described. Compounds 7 gave a series of omega-dialkylaminoalkyl ethers 9, 10 and 11 by reaction of 7 as sodium salts with omega-chloroalkyldialkylamines in DMF solution. Some of compounds 9, 10, 11 showed an appreciable antiarrhythmic and local anesthetic activity in rats and mice, respectively.
