This study concerns detailed analyses of olefinic carbon shieldings in sterols and related cyclic olefins. Included are detailed considerations of olefinic carbon shieldings in monounsaturated sterols and related compounds and in sterols containing homoannular and heteroannular conjugated diene syst
## Abstract A ^13^C magnetic resonance investigation of 22 compounds of the general formula Oο£ΎC^1^(R^1^)C^2^(R^2^)ο£ΎC^3^(R^3^) NR^4^R^4β²^ has been carried out in order to confirm the conformational assignments estimated previously by PMR and IR spectroscopy. The effects of nonplanarity and hindered
