3-(2-Furylmethyl-ene)-1,5-dioxaspiro-[5.5]undecane-2,4-dione.

ABSTRACT: In the title mol-ecule, C(14)H(14)O(5), the 1,3-dioxane ring is in an envelope conformation with the ring C atom common to the cyclo-hexane ring forming the flap. The other five atoms of the 1,3-dioxane ring are essentially planar [maximum deviation from the least-squares plane = 0.041?(3)?Å] and form a dihedral angle of 13.75?(2)° with the furan ring. In the crystal structure, weak inter-molecular C-H?O hydrogen bonds form extended chains along [101].
