title: Synthesis and antitussive activity of 3-azabicyclo[3.2.2]nonane derivatives.
abstract: Mannich bases derived from a number of substituted acetophenones and propiophenones and 3-azabicyclo[3.2.2]nonane have been evaluated for antitussive activity. One of these compounds was as potent as codeine and dextromethorphan in its antitussive activity. The most potent compound of the series, 3-(3-azabicyclo[2.2.2]nonan-3-yl)-4'-benzyloxy-2-methyl propiophenone, also exhibited antimorphine activity. There was no direct correlation between the antitussive effect and antimorphine activity.
