Abstract
Insertion of the rotenoid ‘extra’ C-6 methylene occurs at the isoflavone (IIIa), rather than the isoflavanone (IVa), level of oxidation, in the biosynthesis of amorphigenin; earlier stages use chalcone (Va) with a free 4-hydroxy-group, but the biosynthetically acceptable isoflavone which emerges is not (VIa) but its methyl ether (VIb).Keywords
