were prepared from the 20‐keto compounds by Wittig reaction or a modified Simmons‐Smith reaction. The 13C NMR spectra of these steroids and of 3‐methylene derivatives are analysed. Solvent effects produced by addition of methanol‐d4 in the spectra of the 20‐methylene steroids are correlated with intramolecular hydrogen bonding in the corresponding 20‐ketosteroids.
