The sulfoxide group shows a lot of interesting stereochemical features (2). In thiane-l-oxide the axial conformation (62% of the mixture at -9OOC) is favored by 175 Cal/mole (2). Introduction of a 3,3-dimethyl grouping reverses this axial
Recent studies have shown that the conformational preferenceof the S-0 bond in six membered ring sulphoxdes varies somewhat unpredictably with the atom or group 1n the p-posltlon. Thus thiane l-oxide 1 exists predominantly as
