A number of fused acetal derivatives were prepared in 82-90% yield by tetrabutylammonium peroxydisulfate-mediated oxidative cycloaddition of 1,3-diketones or 1,3-diketoesters to cyclic enol ethers in the presence of a base such as potassium acetate in acetonitrile.

Reaction of manganic acetate in acetic acid with β-diketones and β-ketoesters leads to generation of intermediates, which add efficiently to endocyclic unsaturated enol ethers to afford fused acetals.
Synthesis Of Oxygen Spirocycles By Manganic Acetate Promoted Additions To Exocyclic Enol Ether Derivatives
Mellor, John M.,Mohammed, Shahid
, p. 7107 - 7110 (2007/10/02)
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 enol ethers gives fused acetals and ketals.
