9-(3,4-Dimethoxyphenyl)-3,3,6,6-tetramethyl-4,5,6,9-tetrahydro-3H-xanthene-1,8(2H,7H)-dione

9-(3,4-Dimethoxyphenyl)-3,3,6,6-tetramethyl-4,5,6,9-tetrahydro-3H-xanthene-1,8(2H,7H)-dione

The asymmetric unit of the title xanthene compound, C25H30O5, contains two molecules in which the pyran ring and the dimethoxyphenyl ring are nearly perpendicular to one another [dihedral angles = 86.81 (8) and 84.45 (9)°]. One of the methoxy groups in one mo...
