HIGHLY OXYGENATED FLAVONOID AGLYCONES FROM GUTIERREZIA GRANDIS

Twelve known and nine new highly oxygenated flavonoid aglycones, some of which exhibit 2'-oxygenation, were isolated from Gutierrezia grandis. Key Word Index - Gutierrezia grandis; Compositae; Asterae; highly oxygenated flavonol 3-O-methyl ethers; unusual B-ring oxygenation; brickellin; sarothrin; permethylation.

Synthesis of Distemonanthus benthamianus Flavone

Constitution of a new flavone as 5,6-dihydroxy-3,7,2',4',5'-pentamethoxyflavone (I), isolated from Distemonanthus benthamianus, has now been confirmed by its synthesis using 6-hydroxy-3,5,7,2',4',5'-hexamethoxyflavone (V) as the essential intermediate.V i

Syntheses of Flavonols, Benthamitin and Artemexitin

3,5,6,7,2',4',5'-Heptamethoxyflavone (benthamitin, I) and 5,7,3',4'-tetrahydroxy-3,5'-dimethoxyflavone (artemexitin, II) isolated from Distemonanthus benthamianus and Artemisia monosperma respectively have been synthesised, to provide synthetic evidence f
