A visible light-promoted radical-mediated ring-opening/cyclization of vinyl benzotriazoles has been developed. The method provides an efficient and practical approach to synthesize functionalized phenanthridines from vinyl benzotriazoles with alkyl bromides under mild conditions. Significantly, the readily available and bench-stable vinyl benzotriazoles can serve as valuable alternative radical acceptors during the synthesis of phenanthridines.
已开发出一种可见光促进的自由基介导的乙烯基苯并三唑开环/环化反应。该方法提供了一种高效实用的途径，可在温和条件下由乙烯基苯并三唑与烷基溴合成功能化菲啶。值得注意的是，易于获得且在实验室中稳定的乙烯基苯并三唑可作为菲啶合成过程中有价值的替代自由基受体。
