(E)-1-(2-Hy-droxy-4,6-dimeth-oxy-phen-yl)-3-(4-meth-oxy-phen-yl)prop-2-en-1-one from Kaempferia rotunda Val.

ABSTRACT: The planar -CH=CHC(=O)- fragment (r.m.s. deviation = 0.074?Å) in the title compound, C(18)H(18)O(5), connects the planar hy-droxy-dimeth-oxy-phenyl (r.m.s. deviation = 0.039?Å) and meth-oxy-lphenyl (r.m.s. deviation = 0.021?Å) parts. The central fragment forms a dihedral angle of 13.7?(1)° with the hy-droxy-dimeth-oxy-phenyl part and 32.0?(1)° with the meth-oxy-phenyl part. The hy-droxy group forms an intra-molecular hydrogen bond to the carbonyl O atom.

The planar -CH=CHC(=O)- fragment (r.m.s. deviation = 0.074 Å) in the title compound, C(18)H(18)O(5), connects the planar hy-droxy-dimeth-oxy-phenyl (r.m.s. deviation = 0.039 Å) and meth-oxy-lphenyl (r.m.s. deviation = 0.021 Å) parts. The central fragment forms a dihedral angle of 13.7 (1)° with the hy-droxy-dimeth-oxy-phenyl part and 32.0 (1)° with the meth-oxy-phenyl part. The hy-droxy group forms an intra-molecular hydrogen bond to the carbonyl O atom. ...[more]
