NMR spectral data are given for the A-ring in ten 4-en-3-one steroids, and the strategy of the spectral analysis is described. The data are interpreted in terms of an equilibrium between normal and inverted half-chair conformations, with the normal conformation predominant in all cases except when Z
The 13C N M R spectra of nineteen bromo derivatives of 5ru-cholestan-3-one, cholest4-en-3-one and cholest-5-en-3one have been recorded. The substituent effects are analysed and examined with respect to additivity. The more interesting ys,,, and ylmti effects are considered in detail. KEY WORDS 13C
