N-substituted O-(3-amino-2-hydroxypropyl)oximes of 1,3,3-trimethyl-5-endo-(1-piperidinyl or 4-morpholinyl)-2-oxabicyclo [2.2.2]-octan-6-ones with platelet antiaggregating and local anesthetic activities

The synthesis of a series of N-substituted O-(3-amino-2-hydroxypropyl)oximes of 1,3,3-trimethyl-5-endo-(1-piperidinyl or 4-morpholinyl)-2-oxabicyclo [2.2.2]octan-6-ones is described. Some of these ethers showed strong local anesthetic activity in mice and platelet antiaggregating activity in vitro comparable to that of acetylsalicylic acid, as well as moderate hypotensive, antiarrhythmic and analgesic activities in rats and mice.
