Direct C-H functionalization is very important in the late-stage functionalization of drug molecules. In this context, visible light promoted transformations have emerged as a green strategy for C-H functionalization compared to the conventional strategy. Various methodologies have been developed for the C-H functionalization of different bioactive heterocycles employing this visible light photocatalysis in the presence of either transition metal photocatalysts or organophotoredox catalysts and even in the absence of any photocatalyst. The focus of this review is the demonstration of the efficiency of visible light photocatalysis in the direct C-H functionalizations of pharmacologically active imidazo[1,2-a]pyridines and other related imidazoheterocycles.

可见光促进了咪唑杂环的CH功能化。

直接CH功能化在药物分子的后期功能化中非常重要。在这种情况下,与常规策略相比,可见光促进的转换已成为CH功能化的绿色策略。在过渡金属光催化剂或有机光氧化还原催化剂的存在下,甚至在不存在任何光催化剂的情况下,已经开发出各种方法用于使用可见光光催化的不同生物活性杂环的CH官能化。这篇综述的重点是可见光光催化在药理活性咪唑并[1,2-a]吡啶和其他相关咪唑杂环的直接CH官能化中的效率的证明。
