- Аннотация: Fragmentation of fluorinated 18,19-dihydrothevinols and thevinols under electrospray ionization with collisionally activated dissociation accompanied by the elimination of an amine fragment from the cycle and the subsequent loss of H2O and CH3OH have been studied. For thevinol derivatives with a double bond at C18=C19, the [M + H]+ ions undergo the retro-Diels–Alder fragmentation, the abundance of which depends on substituents at the nitrogen and C20 atoms. The retro-Diels–Alder fragmentation of the [M + H]+ ions of thevinols bearing–CH3,–CH2CH=CH2, and −CH2−◃ groups at the nitrogen atom occurs due to the formation of a protonated diene molecule, whereas the elimination of a neutral diene in thevinols with hydrogen at the nitrogen atom has been observed.
