Starting from the proteinogenic amino acid (S)-serine chiral non-racemic 1,4-diazepanes 4 with a hydroxymethyl residue in position 2 are synthesized and pharmacologically evaluated. The key step in the synthesis is the formation of the bicyclic system 8 by consecutive nucleophilic substitution of the chloropropionamide 7 with primary amines and intramolecular aminolysis. Both reaction steps require catalysis with the Lewis acid Ti(O-iPr)4. Homologation of the piperazine to the 1,4-diazepane ring results in a remarkable improvement of σ1receptor affinity and σ1/σ2selectivity. The 1,4-dibenzyl derivative 4a interacts with a Kivalue of 7.4nM with σ1receptors and shows a 53-fold selectivity for σ1receptors over σ2receptors.
