Abstract
Natural abundance 17O NMR spectroscopic data, in toluene‐d8 at 90°C, were obtained for different classes of steroids, including androstanes, estranes, pregnanes, cholanes and cholestanes. Only routine acquisition parameters were used in combination with linear prediction methods during the processing for eliminating acoustic ringing artifacts. The results are discussed in terms of stereochemical effects on the 17O chemical shift of the various oxygen‐containing functionalities.
