Abstract :
X-ray data for both title molecules display a chair conformation with exo location of cyclopropane moiety and axial or equatorial sulfinyl group. Dynamic 1H and 13C NMR spectroscopy at −95 °С exhibit conformational homogeneity for the first diastereomer and two component chair – twist-boat equilibrium (2:3) for the latter.
