Abstract
The selective demethylation of the 5-methoxyl group of 3-hydroxy-5,8-dimethoxyflavone derivatives could not be carried out by known methods. The synthesis of 8-methoxy compounds has been achieved indirectly by the application of oxidative demethylation using nitric acid. This technique yielded 3,5,7-trihydroxy-8-methoxyflavone, prudomestin (3,5,7-trihydroxy-8,4'-dimethoxyflavone) and limocitrin (3,5,7,4'-tetrahydroxy-8,3'-dimethoxyflavone).
