5-Methoxy-2,2-dimethyl-6-[(2E)-2-methylbut-2-enoyl]-10-phenyl-2H,8H-pyrano[2,3-f]chromen-8-one (calophyllolide)
The title compound, C(26)H(24)O(5), was isolated from calophyllum inophyllum seeds. In the molecule, the phenyl and 2-methylbut-2-enoyl groups are almost orthogonal to the chromene fragment [C—C—C—C torsion angles = 81.4 (3) and −90.1 (2)°, respectively]. In the crystal packing, centrosymmetricall...
