Study by NMR spectroscopy of particular spatial structure of B, 19-bisnortestosterone 9,10-isoanalogs

For two isoanalogs of B,19-bisnortestosterone was carried out a complete assignment of signals in the 1H and 13C NMR spectra with the help of homonuclear and heteronuclear correlation NMR spectroscopy. The predominant conformations of the substances in solutions were derived from the values of coupling constants and nuclear Overhauser effect data.
