A diarylheptanoid intermediate in the biosynthesis of phenylphenalenones in Anigozanthos preissii
Abstract
The incorporation of 1-phenyl-7-(3,4-dihydroxyphenyl)hepta-1,3-dien-5-one and two molecules of cinnamic acid, respectively, into anigorufone by cultured roots of Anigozanthos preissii provides the first experimental evidence for the biosynthesis of a phenylphenalenone from two C6–C3 units via an open chain type diarylheptanoid.
