Through a double cyclization triplet carbonylcarbenes add smoothly to double bonds in the δ and ε position, but do not react intramolecularly with C-H bonds (see scheme). The addition reaction fails if the keto group is replaced with an ester group.

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.
