atoms for the high pharmacological activity of diverse quinuclidine derivatives as compared with the analogous monocyclic and aliphatic compounds [i]. It was shown that the introduction of shielding gem-dimethyl groups into the ~and ~'positions with respect to the nitrogen atom considerably increases the ganglionblocking activity of quinuclidine and piperidine compounds [2, 3] but leads to complete
