Abstract

The dependence of the characteristic fragmentation under electron impact on the spatial orientation of the substituents of cis and trans isomers of 2-(4′-alkoxycarbonylbutyl)-3-hydroxy-4-ureidotetrahydrothiophenes was studied. The possibility of the identification of these isomers on the basis of the intensity ratios of the peaks of the ions formed via two competitive fragmentation pathways with splitting out of the substituents from the C(3) and C(4) positions was demonstrated.
