4-Thia-5α- and 4-thia-5β-androstan-17-ones (1a and 1b) were synthesized in order to obtain the NMR shielding parameters for the thioether C-S bond. The complete NMR assignment of both the proton and carbon atoms for these compounds and substituent-induced shifts (SIS) from the corresponding androstanones (2a and 2b) are presented. A combination of the electric field effect and the anisotropy of the magnetic susceptibility of the C-S bond can successfully reproduced the observed SIS values for these androstanones. © 2005 Elsevier Ltd.
