【 摘 要 】
In the title compound, tetrahydroseselin, C14H16O3, a pyranocoumarin [systematic name: 8,8-dimethyl-3,4,9,10-tetrahydro-2H,8H-pyrano[2,3-f]chromen-2-one] obtained from the hydrogenation of seselin in the presence of Pd/C in MeOH at room temperature, the dihedral angle between the central benzene ring and the best planes of the outer fused ring systems are 6.20 (7) and 10.02 (8)°. In the crystal, molecules show only very weak intermolecular C—H⋯O interactions.
