Condensation of N-substituted 3-azabicyclo[3.3.1]nonan-9-ones with difunctional N,N-, N,S-, and N,O-centered nucleophiles (o-phenylenediamine, 1,2-diphenylethane-1,2-diamine, 2-aminobenzenethiol, cysteine, 2-aminophenol, serine) gave the corresponding spiro heterocyclic compounds fused at the C-9 atom. Treatment of N-tert-butoxycarbonyl-substituted spiro compounds with anhydrous hydrogen chloride resulted in elimination of the tert-butoxycarbonyl group with formation of spiro[3-azabicyclo[3.3.1]nonane-9,2'-azole] hydrochlorides.
