In recent years, the research area of direct C–H bond functionalizations was growing exponentially not only due to the ubiquity of inert C–H bonds in diverse organic compounds, including bioactive natural and nonnatural products, but also due to its impact on the discovery of pharmaceutical candidates and the total synthesis of intricate natural products. On the other hand, more recently, the field of photoredox catalysis has become an indispensable and unparalleled research topic in modern synthetic organic chemistry for the constructions of challenging bonds, having the foremost scope in academia, pharmacy, and industry. Therefore, the development of green, simpler, and effective methodologies to accomplish direct C–H bond functionalization is well overdue and highly desirable to the scientific community. In this review, we mainly highlight the impact on, and the utility of, photoredox catalysts in inert ortho and para C–H bond functionalizations. Although a surge of research papers, including reviews, demonstrating C–H functionalizations have been published in this vital area of research, to our best knowledge, this is the first review that focuses on ortho and para C–H functionalizations by photoredox catalysis to provide atom- and step-economic organic transformations. We are certain that this review will act as a promoter to highlight the application of photoredox catalysts for the functionalization of inert bonds in the domain of synthetic organic chemistry.

光氧化还原催化远程邻位和对位C-H键功能化的最新进展

近年来,直接C-H键功能化的研究领域呈指数级增长,不仅因为惰性C-H键在各种有机化合物(包括生物活性天然和非天然产品)中普遍存在,还因为它对发现的影响候选药物和复杂天然产物的全合成。另一方面,最近,光氧化还原催化领域已成为现代有机合成化学中不可或缺的、无与伦比的研究课题,用于构建具有挑战性的键,在学术界、制药界和工业界具有最重要的范围。因此,科学界早就应该开发绿色、更简单、有效的方法来实现直接 C-H 键功能化,并且非常渴望这样做。在这篇综述中,我们主要强调光氧化还原催化剂在惰性邻位对位C-H 键功能化中的影响和实用性。尽管在这个重要的研究领域已经发表了大量研究论文,包括论证 C-H 官能化的评论,但据我们所知,这是第一篇关注光氧化还原催化的邻位对位C-H 官能化的综述,以提供原子和步骤经济有机转化。我们确信这篇综述将成为突出光氧化还原催化剂在合成有机化学领域惰性键功能化应用的推动者。
