Sui, Jingzhi;He, Yun;Wang, Tao;Liang, Yong;Zhang, Zunting research published 《 Synthesis of Trans-4a,12b/3,4-Dihydrodibenzo[f,h]quinolin-2(1H)-Ones and Dibenzo[f,h]quinolin-2(1H)-Ones via Irradiation of 6-Biphenylpyridine-2(1H)-Ones》, the research content is summarized as follows. The synthesis of trans-4a,12b-dihydrodibenzo[f,h]quinolin-2(1H)-ones, dibenzo[f,h]quinolin-2(1H)-ones and 3,4-dihydrodibenzo[f,h]quinolin-2(1H)-ones via photo-induced annulation of 6-([1,1′-biphenyl]-2-yl)pyridine-2(1H)-ones under irradiation of a 313 nm UV light was described. Trans-4a,12b-dihydrodibenzo[f,h]quinolin-2(1H)-ones were obtained in 82-95% yields when the irradiation time was 3 h. Dibenzo[f,h]quinolin-2(1H)-ones were obtained by irradiating biphenylpyridinones for 12 h in the presence of iodine. Heating the solution of trans-4a,12b-dihydrodibenzo[f,h]quinolin-2(1H)-ones in DMF at 130°C for 24 h gave 3,4-dihydrodibenzo[f,h]quinolin-2(1H)-ones via a double 1,3-H shift. The demonstrated protocols showed the diversity of photo-induced cyclization of biphenylpyridinones.
