Abstract
The Authors describe the synthesis of some quaternary salts of the hexahydro-1H-2,6-methanopyrrolo[1,2-a]pyrazines mono or disubstituted at carbon-4. These were obtained directly by cyclization of the corresponding diazabicyclooctanes, by formation of a substituted ethylenic bridge between the two nitrogen atoms. The compounds were pharmacologically screened; the hypothesis of enhancement of curare-like activity in comparison with the unsubstituted derivatives was not confirmed.
