Photoinduced Intramolecular Addition of 3-Acyl-2-haloindoles to Alkenes Shen-Ci Lu Xiao-Yong Duan Zong-Jun Shi Bing Li Yu-Wei Ren Wei Zhang Yong-Hui Zhang Zhi-Feng Tu 10.1021/ol901498f.s003 https://acs.figshare.com/articles/dataset/Photoinduced_Intramolecular_Addition_of_3_Acyl_2_haloindoles_to_Alkenes/2830798 1,2-Fused indoles and pyrroles were prepared via an efficient intramolecular photoaddition reaction of 1-(ω-alkenyl)-2-haloindole-3-carbaldehydes and 1-(ω-alkenyl)-2-chloropyrrole-3-carbaldehydes. The presence of an acyl group was necessary for the photocyclization reactions. The halogen-atom-retained exo- and endo-cyclization products were generally produced with results similar to those of an atom-transfer cyclization reaction. In contrast, unsaturated cyclization products were obtained in the photoreaction of substrates having methyl groups on the vinyl group. 2009-09-03 00:00:00 Photoinduced Intramolecular Addition photocyclization reactions methyl groups acyl group vinyl group intramolecular photoaddition reaction alkenyl cyclization products
