Li, Lingzi published the artcilePhotochemical electrocyclization and leaving group expulsion with a naphthothiophene-2-carboxanilide linked to a chromophore, Recommanded Product: 4-Methoxy-N-methylaniline, the main research area is photochem electrocyclization leaving group expulsion chromophore naphthothiophene carboxanilide.
A naphthiothiophene-2-carboxanilide bearing a leaving group at the C-3 position undergoes efficient electrocyclic ring closure and leaving group expulsion upon direct photolysis. The reaction occurs in the triplet excited state and can be sensitized by thioxanthone. Thioxanthone as chromophore can also be covalently attached to amide nitrogen by a trimethylene linker, and the photoreaction is equally efficient. Quenching studies show that the triplet excitation is localized primarily on the naphthothiophene moiety, due to rapid exothermic energy transfer from the thioxanthone chromophore. Acriflavin dye is capable of sensitizing the photoreaction at 450 nm, but the quantum yield is low in this case.
