STRUCTURE DETERMINATION OF MELANERVIN, THE FIRST NATURALLY OCCURING FLAVONOID OF THE TRIPHENYLMETHANE FAMILY
Seligmann, O.,Wagner, H.
, p. 2601 - 2606 (1981)
From the flowers of Melaleuca quinquenervia (Myrtaceae) besides the flavonones strobopinin and kryptostrobin a new 8-aryl-flavonone has been isolated and shown to be (2,4-dihydroxy-6-methoxy)tolyl-3-(5,7-dihydroxy-6-methyl)flavanonyl-8-phenylmethane, mainly by degradation, MS, 1H- and 13C-NMR-spectroscopy.The new flavanone represents the first naturally occuring triphenylmethane compound.

Rottlerin, a natural product isolated from Mallotus philippensis, is associated with a range of biological activities. Its chemical structure is featured by two different substituted phloroglucinol units linked by a methylene group. In this study, we accomplished a total synthesis of rottlerin using phenol-aldehyde condensation as the key reaction. By our method, gram-scale preparation of the two structural subunits was achieved, and rottlerin was obtained in a longest eight linear step with 20% overall yield. Our study provides a practical solution for obtaining the sample of rottlerin in an efficient way.

Aurentiacin 7 has been isolated from Pityrogramma triangularis var. pallida and synthesised from phloroacetophenone 1 in several steps. All the new products have been characterised on the basis of spectral data and micro analysis.
