5-Hy-droxy-6-[(E)-2-phenyl-ethen-yl]-5,6-dihydro-2H-pyran-2-one isolated from Goniothalamus ridleyi.

ABSTRACT: In the title compound, C(13)H(12)O(3), the pyran ring adopts a half-chair conformation with a C atom deviating from the least-squares plane of the remaining ring atoms by 0.606?(2)?Å. This plane and that of the benzene ring make a dihedral angle of 44.18?(6)°. In the crystal, mol-ecules are linked through O-H?O hydrogen bonds into infinite chains along the b axis, and these chains are cross-linked by C-H?O hydrogen bonded into sheets lying parallel to the bc plane. The layers are further connected via C-H?? inter-actions to form a three-dimensional supra-molecular structure.
