Carbon-13 NMR spectra of about 40 polyoxypregnanes were determined at 25.146 MHz on a Pulsed FT NMR spectrometer (1). C-13 NMR spectra have been far more informative than proton NMR spectra for structural analyses of the C/D-cis polyoxypregnanes,\* both because of the enormous sensi-tivity of C-13 c
