Oxidative addition, promoted by manganic acetate, of β-dicarbonyl compounds to enol lactones and related enol derivatives having an exocyclic double bond affords spirocyclic products, and addition to endocyclic enolethers gives fused acetals and ketals.

Reaction of manganic acetate in acetic acid with β-diketones and β-ketoesters leads to generation of intermediates, which add efficiently to endocyclic unsaturated enolethers to afford fused acetals.
