英文摘要

To investigate the structural form of gossypol and gossypolone Schiff′s bases, seven relevant Schiff′s bases were synthesized and the electrospray ionization-tandem mass spectrometry (ESI-MS/MS) with low-energy collision-induced dissociation was used to analyze their fragmentations. A common fragmentation pathway with the loss of RNH2 from those schiff′s bases quasi-molecular ions was observed and proposed on the basis of their MS/MS spectra data. This common pathway indicated that those Schiff′s bases existed mainly as the enamine form not the imine form previously showed in most reports. (C) 2009 Yu Yin Cui.
