omega-Dialkylaminoalkyl ethers of 5-(arylmethylene)-1,3,3-trimethyl-2- oxabicyclo[2.2.2]octan-6-hydroxyimines with platelet antiaggregating and other activities.

The synthesis of omega-dialkylaminoalkyl ethers 3 by the reaction of some 5-(arylmethylene)-1,3,3-trimethyl-2-oxabicyclo[2.2.2]octan-6- hydroxyimines as sodium salts with the appropriate omega-chloroalkyldialkylamine in DMF solution is described. Some aminoethers 3 showed strong platelet antiaggregating activity in vitro superior to that of acetylsalicylic acid, as well as weak antiarrhythmic activity in rats and moderate infiltration anesthesia in mice.
