Guatteria ouregou

In Guatteria ouregou the unusual functional grouping and substitution pattern of gouregine (17) and the coproduction of the aporphine melosmine (46) leads to the suggestion that 17 may be formed by oxidation of 46 at positions 11-1 la or 7a-l la, followed by rearrangement of the biarylic bond, as indicated in Scheme... [Pg.321]

Finally, to the above list of compounds can be added the recently characterized gouregine (11) (Leboeuf et al. 1982), which has an unusual oxygenation pattern and bears two methyl substituents at C-a and has been isolated from Guatteria ouregou Dun. (Annonaceae). [Pg.105]
