3-[(5-Methyl­furan-2-yl)methyl­ene]-1,5-dioxaspiro­[5.5]undecane-2,4-dione

There are two crystallographically independent mol­ecules in the asymmetric unit of the title compound, C(15)H(16)O(5). In each, the 1,3-dioxane ring is in an envelope conformation with the C atom common to the cyclo­hexane ring forming the flap. The dihedral angles between the five essentially plan...

description There are two crystallographically independent mol­ecules in the asymmetric unit of the title compound, C(15)H(16)O(5). In each, the 1,3-dioxane ring is in an envelope conformation with the C atom common to the cyclo­hexane ring forming the flap. The dihedral angles between the five essentially planar [maximum deviations from the least-squares planes of 0.049 (3) and 0.042 (3) Å] atoms of the 1,3-dioxane ring and the furan ring in the two mol­ecules are 7.15 (1) and 6.80 (1)°. The crystal structure is stabilized by weak inter­molecular C—H⋯O hydrogen bonds.
