Methyl 3,3,6,6-tetra-methyl-1,8-dioxo-4,5,7,9-tetra-hydro-2H-xanthene-9-carboxyl-ate.

ABSTRACT: The title mol-ecule, C₁₉H₂₄O₅, is built by annulation of a half-chair cyclo-hexenone and a twist-cyclo-hexenone to a flat 4-H-pyrane boat. In the crystal, mol-ecules are connected via van der Waals inter-actions and C-H⋯O hydrogen bonds.

Project description:In the title compound, C23H24F2O3, the central pyran ring has a flat-boat conformation, whereas the two fused cyclo-hexenone rings adopt envelope conformations, with the C atom bearing the dimethyl substituent being the flap atom in each case.
