以Rose Bengal为有机染料光催化剂, 在可见光照射下发展了2-芳基吲哚结构的自由基烷氧羰基化反应构建酯基取代的吲哚[2,1-a]异喹啉酮骨架. 在温和的条件下, 能以良好到优秀的收率得到结构多样的吲哚[2,1-a]异喹啉酮类化合物. 该方法具有反应条件温和、利用可见光为能量来源、无需金属催化剂和价廉易得的肼甲酸酯为酯基来源等优点, 更加绿色环保.

关键词: Rose Bengal, 有机染料, 可见光, 2-芳基吲哚, 吲哚[2,1-a]异喹啉酮

A visible-light-mediated organic dye photoredox-catalyzed alkoxycarbonylation of 2-aryl-N-acryloyl indoles to give valuable indolo[2,1-a]isoquinoline derivatives has been developed. With this approach, a variety of ester-substituted indolo[2,1-a]isoquinolines are prepared in moderate to good yields. Mild reaction conditions, metal free, visible light as a traceless energy source, economical and environmentally benign Rose Bengal as the catalyst, stable and easily accessible starting materials all make this methodology more attractive.

Key words: Rose Bengal, organic dye, visible-light, 2-aryl-indoles, indolo[2,1-a]isoquinolines
