Phytochemicals from Echinacea and Hypericum: A Direct Synthesis of Isoligularone.

George A Kraus1, Jaehoon Bae, Junwon Kim.   

Abstract

Reaction of trienes with α,β-unsaturated aldehydes produces bicyclic products via a tandem Diels-Alder/ene reaction. The adduct from tiglic aldehyde was converted into isoligularone by conversion to a furan followed by benzylic oxidation.
