摘要: Fragmentation of ethyl(18-alkoxybicyclo[4.3.0]-3-nonene-7-carboxylates) was found to depend on the annulation rings. Following ionization, cis-annulated isomers lose alcohol and benzene, while trans-isomers fragment by other reaction paths. The regiospecificity elimination from both ester ether groups determined using deuterium-labelled analogues. A mechanism is discussed which rationalizes differences observed in spectra isomers.
