 Abstract: The relative orientation of substituents in the opposite rings of one of the isomeric 4,7-Dichloro-5,8,12,15-tetramethoxy-13,6-bis[4-(2-methoxycarbonylphenyl) butyl][2.2]paracyclophanes was determined by establishing by NOE their orientation relative to the bridge protons, which thus served as ‘space-spy nuclei’. The mutual orientation of these bridge protons was ascertained by the analysis of their coupling constants, obtained from a phasesensitive COSY spectrum. The 1H and 13C resonances were assigned with the aid of 1H COSY and 1H/13C inversely correlated spectra.
