Synthetic Studies on the Flavone Derivatives. XII. Synthesis of 2',3',5'- and 3',4',5'-Trioxygenated Flavones

Two unusual flavones, 5,5'-dihydroxy-2',3',6,7-tetramethoxyflavone (1) from Gardenia cramerii and 4',5-dihydroxy-3',5',6,7-tetramethoxyflavone (6) from Artemisia mesatlantia, and their position isomers were synthesized to investigate the structural correlation in terms of spectral data.The structure of the flavone from G. cramerii is discussed.Keywords: 5,5'-dihydroxy-2',3',6,7-tetramethoxyflavone; 2',5-dihydroxy-3',5',6,7-tetramethoxyflavone; 5-hydroxy-2',3',5',6,7-pentamethoxyflavone; 3',5-dihydroxy-4',5',6,7-tetramethoxyflavone; 4',5-dihydroxy-3',5',6,7-tetramethoxyflavone; 5-hydroxy-3',4',5',6,7-pentamethoxyflavone.

Constitution of Artemisia mesatlantica Pigment: A Synthetic Study

Synthesis of 5,4'-dihydroxy-6,7,3',5'-tetramethoxyflavone (1) using 4'-benzyloxy-5,6,7,3',5'-pentamethoxyflavone (2) as the key-intermediate is described.The synthetic (1) differs from the natural sample isolated from Artemisia mesatlantica Phytochemistr
