The first stereoselective synthesis of acis,cis‐configured vicinal triamine was achieved, starting fromN‐cyclohexenylpyrrolidone (10). The reaction sequence consists of the stereoselective construction of thetrans‐configured 1,3‐diamide14,trans‐to‐cisisomerization via enols or enamines, and subsequent highly stereoselective reduction of the intermediate imine17Dto the amine18A. The postulated reaction pathway explains the observed stereoconvergence and is supported by calculation of the heats of formation of its intermediates at the PM3 level. LiAlH4reduction of18Ayielded the tetracyclic aminal19, which was converted into the pyrrolidinylquinoxaline7, which showed low to moderate affinity towards κ and σ1receptors.
