Methyl 3,3,6,6-tetra­methyl-1,8-dioxo-4,5,7,9-tetra­hydro-2H-xanthene-9-carboxyl­ate

ABSTRACT: The title mol­ecule is built by annulation of a half-chair cyclo­hexenone and a twist-cyclo­hexenone to a flat 4-H-pyrane boat. In the crystal, mol­ecules are connected via van der Waals inter­actions and C—H⋯O hydrogen bonds.
