1-(2,6-Dihydr-oxy-4-methoxy-phen-yl)-3-phenyl-propan-1-one.

ABSTRACT: The title compound, C(16)H(16)O(4), a dihydro-chalcone, was isolated from the rhizomes of Etlingera littoralis. The mol-ecule is twisted with a dihedral angle of 71.69?(6)° between the two aromatic rings. The propanone unit makes dihedral angles of 4.07?(6) and 73.56?(7)°, respectively, with the 2,6-dihydroxy-4-methoxyphenyl and phenyl rings. The meth-oxy group is approximately coplanar with the attached benzene ring with a dihedral angle of 1.74?(10)°. An intra-molecular O-H?O hydrogen bond generates an S(6) ring motif. In the crystal, inter-molecular O-H?O hydrogen bonds link the mol-ecules into chains along [201]. A ?-? inter-action with a centroid-centroid distance of 3.5185?(6)?Å is also observed.
