4-Methoxycinnamic acid - An unusual phenylpropanoid involved in phenylphenalenone biosynthesis in Anigozanthos preissii

An unusual phenylpropanoid, 4-methoxycinnamic acid, was used in 13C-labeled form as a substrate to demonstrate its incorporation as an intact unit during the biosynthesis of 4′-methoxyanigorufone, which is reported here for the first time as a natural product.
