A novel process for producing 3-formylcyclopentanone derivatives which are useful intermediates for syntheses of five-membered ring compounds such as prostaglandins is disclosed. In the process, 3-formylcyclopentanone derivatives are produced starting from .beta.-dicarbonyl compounds and azides through several-step reactions.
