惰性C—H键的不对称活化官能团化为手性功能分子的高效构筑提供了全新的合成思路, 是当前有机合成化学的研究热点之一. 其中, 过渡金属催化导向基团辅助的C—H键不对称官能团化反应是该研究领域的一个主要分支. 相比于传统的导向基团, 氧化型导向基团既能起到定位作用, 又能作为分子内氧化剂驱动催化循环, 因此可以在无需外加氧化剂的条件下通过选择性碳氢键转化构建各种杂环或官能团化产物. 近年来, 随着一系列新兴手性过渡金属催化剂的不断出现, 基于氧化型导向基团策略的C—H键不对称官能团化反应也得到快速发展, 成为构建高附加值对映体富集手性化合物的一种重要手段. 总结了自2012年以来基于上述策略的C—H键不对称官能团化反应进展, 并对该策略存在的局限性和发展前景进行分析和展望.

The development of asymmetric functionalization of inert C—H bond is one of the most popular research topics in organic synthesis, which provides innovative and efficient pathways to access chiral functional molecules. Among which, the directing group-assisted transition metal-catalyzed asymmetric C—H bond functionalization represents an important branch in this field. In comparison with the traditional directing groups, the oxidizing directing groups can not only govern the site-selectivity in C—H activation but also serve as an internal oxidant to drive the catalytic process, which enables the formation of diverse heterocycles and other products via C—H activation in the absence of any external oxidant. In the last decade, the emergence of diverse new chiral metal catalysts has boosted the rapid development of asymmetric C—H bond functionalization using oxidizing directing groups, constituting an important method to assemble the value-added chiral molecules. The advance of asymmetric C—H bond functionalization using oxidizing directing groups since 2012 is summaried, the limitation in this field is also analyzed and the outlook of this area is prospected.
