γ,δ- and δ,ε-unsaturated aldehydes from γ- and δ-lactones in one step: Preliminary communication
Giersch, Wolfgang,Naef, Ferdinand
, p. 1697 - 1703 (2004)
A one-step transformation of δ- and δ-(spiro)lactones into δ,δ- and δ,ε-unsaturated aldehydes with an excess of formic acid in the vapor phase over a supported manganese catalyst is described for the first time. The scope and limitations of this new reaction are shown with different lactones as substrate, and a mechanistic rationale is proposed.
