| Abstract: | The photo‐irradiation of chalconoid‐like compounds; (2E,4E)‐1‐(2‐hydroxyaryl)‐4‐methyl‐5‐phenylpenta‐2,4‐dien‐1‐ones to 4‐flavanoids in solution phase has been described. The molecular scaffold of the probed substrates is responsive to intramolecular cyclization as well as cis‐trans isomerizations and photoproducts corresponding to both of reactions have been realized also. The formation of photoproducts has been explained on the basis of excited state intramolecular proton transfer that further depends upon the different substituents present on the phenolic moiety. |
