Acridone alkaloids. X. 13C-Nuclear magnetic resonance spectra of acridone alkaloids.

open access: yesChemical and Pharmaceutical Bulletin, 1983
The 13C-nuclear magnetic resonance spectra of twenty-seven acridone alkaloids including angular pyrano [2, 3-c] acridones and linear pyrano [3, 2-b] acridones have been analyzed and assigned. The information should be useful for the structure elucidation of new acridone alkaloids.
