O-(2-dialkylaminoethyl)oximes of 5-(arylmethylene)-1,3,3-trimethyl-2-oxabicyclo [2.2.2]octan-6-ones with hypotensive, antiarrhythmic and other activities.

The synthesis of some O-(2-dialkylaminoethyl)oximes of 5-[(4-methoxy- or 4-methylthiophenyl)methylene]-1,3,3-trimethyl-2-oxabicyclo[2.2.2] octan-6-ones 5 by reaction of the corresponding oximes as sodium salts with the appropriate 2-chloroethyldialkylamine in dry ethanol solution is described. Some aminoethers 5 showed appreciable hypotensive and antiarrhythmic activities in rats, as well as a weak platelet antiaggregating activity in vitro and a moderate infiltration anesthesia in mice.
