3,9-Di-tert-butyl-2,4,8,10-tetra­oxaspiro­[5.5]undeca­ne

Abstract

The title compound, C15H28O4, was prepared by the condensation of pivalaldehyde with penta­erythritol. In the crystal, the two halves of the mol­ecule are related by a crystallographic twofold rotation axis passing through the central spiro-C atom. The two non-planar six-membered heterocycles both adopt chair conformations with the two tert-butyl groups both located in the equatorial positions
