碳氢键活化被认为是合成有机化学中最具吸引力的技术之一, 因为它有可能缩短合成路线, 并与传统合成策略相互补. 近年来, 受益于基础知识的显著增长, C(sp3)—H键不对称自由基反应的新想法不断涌现, 随之而来的是大量新的催化方法. 综述了自2020年以来报道的C(sp3)—H键对映选择性自由基反应, 讨论了通过各种途径(如能量转移、单电子转移、氢原子转移等)直接或者间接断裂C—H键形成碳自由基中间体, 随后构建手性C—C、C—N和C—O键的方法.

The activation of carbon-hydrogen bonds is considered one of the most attractive techniques in synthetic organic chemistry due to its potential to shorten synthetic routes and complement traditional synthetic strategies. In recent years, owing to the significant growth in foundational knowledge and advancements in various technologies, new ideas about asymmetric radical reactions have continuously emerged, leading to numerous novel catalytic methods. The enantioselective radical reactions involving C(sp3)—H bonds published since 2020 are reviewed. The methods of directly or indirectly breaking C—H bonds through various pathways, such as energy transfer, single-electron transfer, and hydrogen atom transfer, to form carbon radicals and subsequently construct chiral C—C, C—N, and C—O bonds, are discussed.

Key words: C—H bond, radical reaction, enantioselectivity
