Description The conjugative ability of a spirocyclopropane on 4-en-3-one steroids was studied with the help of C-13 NMR and two-dimensional experiments such as COSY and NOESY. The conformational analysis of the A ring of these compounds indicates a 'normal' (1-alpha,2-beta)- half-chair conformation rather than the expected 'inverted' (1-beta,2-alpha)- half-chair conformation. Application of the modified McConnell equation for the shielding influence of the cyclopropane aids the analyses.
