The mass spectra of oxygen heterocycles. Part (V). The mass spectra of 2′-hydroxyflavonoids
Abstract
The mass spectra of some 2′-hydroxyflavonoids have been examined and found to differ considerably from those flavonoids not bearing a 2′-hydroxy-group. The breakdown of various classes of flavonoid bearing this group has been explored. A new synthesis of flav-3-enes, having analogies to the rearrangements occurring in the mass spectrometer is outlined.
