Aminoethers of (+)-1,3,3-trimethyl-2-oxabicyclo[2.2.2]-octan-6-hydroxyimine with hypotensive activity. II

The synthesis of a series of N-substituted 3-amino-2-hydroxypropyl ethers (III a-1) starting from (+)-1,3,3-trimethyl-2-oxabicyclo [2.2.2]-octan-6-hydroxyimine is described. Some of these compounds showed a remarkable hypotensive and a weak bradycardic activity in rats, as well as a moderate local anesthetic activity in mice. All compounds were found to be devoid of antiarrhythmic activity in rats and of beta-blocking activity in dogs.
