Wittig, aldol and Wittig-Horner reactions have been used to synthesize new diarylheptanoids, which are putative intermediates in phenylphenalenone biosynthesis in plants. The Wittig-Horner approach was most suitable and gave significantly higher yiel

For several decades isotope labelling techniques have been the indispensable tools used to unravel pathways of secondary product biosynthesis. NMR spectroscopy, together with mass spectrometry, is the most effective measuring technique used in the an

Three fused octacyclic phenylphenalenone dimers were isolated from Musa acuminata: Anigorootin, which was first isolated from Anigozanthos flavidus and hitherto represented the only compound of that type, the new 4′-hydroxy-anigorootin, and 4′,4

HPLC-NMR spectroscopy was employed to observe isotopically labelled intermediates of the phenylpropanoid metabolism in Anigozanthos preissii. Hydroxylation of dihydrocinnamic acid to dihydro-p-coumaric acid and the reversible interconversion between

Feeding experiments using 13C labelled precursors and NMR spectroscopic studies revealed general biosynthetic incorporation of phenylalanine and variable incorporation of cinnamic acid, p-coumaric acid, caffeic acid and ferulic acid into phenylphenal
