title: [Synthesis, stereochemistry and analgesic action of 3,7-diazabicyclo[3.3.1] nonan-9-ones and 1,3-diazaadamantan-6-ones].
abstract: The 1,3-diazaadamantan-6-ones 13-18 are synthesized from the 4-piperidones 1-3. Different conditions lead to stereoisomeric structures. The 3,7-diazabicyclo[3.3.1]nonan-9-ones 8 and 9 show similar geometrical isomerisms. The configuration is determined by means of 1H-NMR and 13C-NMR spectroscopic data. Whereas the diazabicyclo[3.3.1]nonanones 7 and 12 show opioid-like effects, the diazaadamantanone 13 is a peripheral analgesic.
