Conformationally constrained 5-tert-butyl 1,3-oxathiane was synthesized and oxidation led to the diastereoisomeric sulfoxides and the respective sulfone. Stereoelectronic effects are discussed for these compounds and their corresponding 2-carbanions. pKa values are calculated for these compounds and compared with the respective 1,3-dithiane-derived sulfide, the sulfoxides, and the sulfone.
