Abstract: In the title compound, C₁₆H₂₀O₄S, the epoxide ring is trans to the p-tolyl group and cis to the dioxolane moiety. The furanose ring adopts a conformation in which the furanose and epoxide O atoms are on the same face of the molecule (E_O) and the p-tolyl group adopts the conformation favored by the exo-anomeric effect, gauche to the ring O atom and anti to the ring C atom.
