The title compound, 2,5-bis(4-methylphenylsulfonyloxy-methyl)oxolane-3,4-diyl diacetate, C24H28O11S2, lies on a crystallographic twofold axis. It adopts a perfect twist 3(4)T conformation in the solid state. The puckering parameters of the tetrahydrofuran ring are q = 0.32 (8) A and rho = 92.3 (5) degrees. The acetyl groups are planar, with the non-H atoms deviating less than 0.002 (3) A from their mean plane. They have an (S)-cis conformation with the C-O and C = O bonds eclipsed, and each acetyl group is orientated with the C = O group syndiaxial to the C-H bond at the ring C atom to which the group is attached.
