We report facile and versatile procedures for the synthesis of exo - and endo -isomeric spirocyclic hybrids of pharmacophoric (1 R ,5 S)-8-azabicyclo[3.2.1]octane (nortropane) and 1,3-oxazinan-2-one fragments. Our approach consists of the hydrocyanation of endo - and exo -isomeric N -Cbz-protected nortropane-3-spiroepoxides, the reduction of hydroxy nitriles into amino alcohols, the synthesis of N -alkylated amino alcohols via reductive amination, the spirocyclization of the amino alcohols, N -alkylation of the unsubstituted 1,3-oxazinan-2-one fragment in the spiro compounds, and removal of the Cbz protecting groups.
