Structure elucidation of annoheptocins, two new heptahydroxylated C-37 acetogenins by high-energy collision-induced dissociation tandem mass spectrometry

Abstract
Collision-induced dissociation (CID) of lithiated molecules generated by liquid SIMS (LSIMS) from two new natural compounds, annoheptocin A and B, led to their structural elucidation. Mass spectrometry (MS) and tandem mass spectrometry (MS/MS) investigations of their acetonide derivatives displayed obvious differences of reactivity of the lithiated dioxane and dioxolane rings towards CID, The 1,3-dioxane (six-membered) ring could be the target of hydrogen rearrangement processes, leading to the formation of a tetrahydrofuran ring through the loss of a molecule of acetone.
