3-Methylflavones characterization revisited: complete assignment of 1H and 13C NMR data



Ten 3-methylflavone derivatives were studied. Previously reported NMR data of some derivatives were corrected and/or completed, including the complete assignment of the two known natural derivatives. The complete 1H and 13C NMR assignments were achieved by combination of one-dimensional and two-dimensional NMR experiments. Copyright © 2013 John Wiley & Sons, Ltd.
