Abstract
The PMR and proton magnetic double resonance (PMDR) spectra were obtained for five cis and trans isomer pairs of substituted 4-amino-3-hydroxythiophanes. A comparison of the PMR parameters of the cis and trans isomers made it possible to formulate the characteristic differences in their spectra. On the basis of the data obtained, the trans configuration is proposed for the ethoxycarbonylamino and hydroxy groups in 4-ethoxycarbonylamino-3-hydroxy-3-cyanothiophane, the configuration of which has not been previously determined.
