(6R*,10R*)-Dimethyl 1,4-dioxaspiro­[4.5]decane-6,10-dicarboxyl­ate

The title compound, C₁₂H₁₈O₆, is in the usual chair conformation with the two ester functions in a 1,3-trans orientation. With a value of 1.439 (2) Å, the pseudo-axial C-O bond of the 1,3-dioxolane ring is slightly longer than the corresponding equatorial C-O bond of 1.424 (3) Å. The O-C-O angle of the dioxolane ring is 106.25 (17)°.
