N-Substituted Acridone Alkaloids From Toddaliopsis Bremekampii (Rutaceae: Toddalioideae) of South-Central Africa

Phytochemistry, 2005
Toddaliopsins A-D, four novel 1,2,3-trioxygenated acridone alkaloids, have been isolated from the leaves of Toddaliopsis bremekampii. Toddaliopsins B-D are the first reported acridone alkaloids with substituted N-methyl groups, in the light of which the ...

The biogenesis of acridone alkaloids

Journal of the Chemical Society D: Chemical Communications, 1970
The similarity in substitution pattern between xanthones and acridone alkaloids and the analogous cyclisation reactions observed for 2-hydroxy- and 2-amino-benzophenones suggest that related biogenetic pathways may be involved.

Mass Spectra of Acridone Alkaloids

Journal of the Chinese Chemical Society, 1989
AbstractThe mass spectra of a variety of simple acridones, prenylacridones, pyranoacridones, dihydropyranoacridones, and furoacridones are presented and discussed. The results illustrate that the characteristic fragmentation patterns are of considerable utility in the application of mass spectrometry to structure elucidation in the acridone alkaloids.

Quinoline, quinazoline, and acridone alkaloids

Natural Product Reports, 1984
The most interesting new alkaloids are the acridones that contain tropone rings, which have been isolated from Citrus species. Emphasis this year is again on synthesis, with highlights including the first use of copper acetylides in the synthesis of furoquinolones, the synthesis of the (1,l -dimethylallyl)quinolinone buchapine, and developments in the ...

Biomimetic synthesis of acridone alkaloids

Journal of the Chemical Society, Perkin Transactions 1, 1977
Cyclisations of 2′-amino-, 2′-acetylamino-, or 2′-methylamino-2-methoxybenzophenones occur in the presence of sodium hydride in dimethyl sulphoxide to give acridone alkaloids. This cyclisation has relevance to the biosynthesis of these alkaloids. An alternative cyclisation can occur, giving 4-arylquinolines or 4-arylquinolones.
