Abstract:<p>This study elucidates
the gas-phase fragmentation pathways of a series of biologically active
benzofuran neolignans (BNs) and dihydrobenzofuran neolignans (DBNs) by means of
electrospray ionization accurate-mass tandem and sequential mass spectrometry (ESI-MS/MS
and ESI-MS<sup>n</sup>) and thermochemical data estimated by using Computational
Chemistry and the B3LYP/6-31+G(d,p) model. In their deprotonated forms, these compounds
produced more diagnostic product ions as compared to the corre… Show more
