Abstract
Herein, the synthesis and crystal structure of 7-hydroxy-3-(2-methoxyphenyl)-2-trifluoromethyl-4H-chromen-4-one, C17H11F3O4, are reported. This isoflavone is used as a starting material in the preparation an array of potent and competitive FPR antagonists. The pyran ring significantly deviates from planarity and the dihedral angle between the benzopyran mean plane and that of the exocyclic benzene ring is 88.18 (4)°. In the crystal, O—H...O hydrogen bonds connect the molecules into C(8) chains propagating in the [010] direction.
