Article abstract of DOI:10.1248/cpb.39.2173

Exposure of the (E)-isomer (4E) of 2-(3,4,5-trimethoxyphenyl)-4-(3,4-methylenedioxyphenyl)-4-oxo-2-butenon itrile (β-cyanochalcone) in the solid state to sunlight led to unusual dimerization through isomerization to give an unsymmetrical E-Z dimer (7) alo
