New chiral heterocyclic compounds, (3aS, 6R)-5-oxa-7, 8a-diazaperhydroazulen-8-ones (2a-c), were synthesized and their absolute configurations were determined by X-ray analysis. The reaction of (3aS, 6R)-2a-c with diethylzinc proceeded under mild conditions with extremely high diastereoselectivity.
