Heating of 3,7-di(tert-butyl)-1,5-dimethyl-3,7-diazabicyclo[3.3.1]nonan-9-one with hydro-bromic acid gave 1,5-dimethyl-3,7-diazabicyclo[3.3.1]nonan-9-one (1,5-dimethylbispidin-9-one). Condensation of this compound or 1,5-dimethylbispidin-9-ol with dialdehydes afforded new compounds containing two 1,3-diazaadamantane moieties in one molecule, which are connected either directly or through spacers.
