1 H and 13 C NMR spectroscopic data for 5α‐androstanes and halo‐5α‐androstanes with different substituents at positions C‐3, C‐9, C‐11 and C‐17 were examined and assigned by a combination of 1D and 2D NMR experiments. The substituent effects on the 13 C chemical shifts were compared with those of epi ‐androsterone, used as a reference compound. The coupling constants n J ( 19 F, 13 C) were measured for compounds 6, 8, 11 and 14. Copyright © 2005 John Wiley & Sons, Ltd.
