- Structural Confirmation of Eriodictyol 7-Methyl Ether, a New Flavone Occurring in Wyethia glabra Nutt
-
5,3',4'-Trihydroxy-7-methoxyflavanone (III), isolated from Wyethia glabra Nutt. , designated as eriodictyol 7-methyl ether, has been synthesised by the cyclization of 3,4-dibenzyloxy-2'-hydroxy-4',6'-dimethoxychylkone (I), followed by concerted debenzylation and partial demethylation of the resulting flavanone using anhydrous AlCl3 in acetonitrile.
