Visible-light photoredox catalysis is a powerful and attractive strategy for organic molecule activation and new reaction design owing to its environmental-friendly characteristics and unique catalytic mechanisms, and has found wide applications in organic synthesis. This catalytic strategy enables controllable generation of diverse nitrogen-centered radicals (NCRs) under mild conditions, providing access to construction of diverse nitrogen-containing compounds. In this review, we critically illustrate the recent advances in the field of visible-light photoredox-catalyzed cyclization of nitrogen-centered radicals, based on the different radical precursors and activation modes. Wherever possible, particular emphasis is also put on working models and synthetic applications.

可见光光氧化还原催化由于其环保特性和独特的催化机理而成为有机分子活化和新反应设计的有力且有吸引力的策略，并已在有机合成中得到广泛应用。这种催化策略能够在温和的条件下可控地产生多种以氮为中心的自由基（NCR），从而提供了构建多种含氮化合物的途径。在这篇综述中，我们基于不同的自由基前体和活化模式，以批判性的方式说明了可见光光氧化还原催化的氮中心自由基环化领域的最新进展。只要有可能，还应特别强调工作模型和合成应用程序。
