双环[1.1.0]丁烷和氮杂双环[1.1.0]丁烷衍生硼酸酯(BCB-Bpins)兼具高环张力与硼官能团的独特反应活性,其转化通常以环张力释放为核心驱动力。本文系统综述了近年来BCB-Bpins转化反应的研究进展,并将其归纳为三类主要途径:离子型转化,包括硼酸酯复合物参与的亲核1,2-迁移;自由基型转化,包括环张力释放驱动的自由基加成反应;过渡金属催化的立体选择性转化,重点涉及钯或铱催化下的立体选择性与不对称双官能团化反应。本文还结合代表性实例,对反应设计、区域与立体选择性控制及机理认识进行了总结与讨论,并对该领域在新型催化不对称转化和反应模式拓展方面面临的挑战与发展方向进行了展望。

Bicyclo[1.1.0]butane- and azabicyclo[1.1.0]butane-derived boronic esters (BCB-Bpins) combine high ring strain with the versatile reactivity of organoboron groups, and their transformations are typically driven by strain release. This review summarizes recent advances in BCB-Bpin chemistry through three main pathways: ionic pathways, such as nucleophilic 1,2-shift in boronate complexes; radical approaches, including strain-release-driven additions to BCB-Bpins; and transition-metal-catalyzed stereoselective functionalizations, especially Pd- and Ir-catalyzed stereoselective and asymmetric difunctionalizations. Representative studies, mechanistic features, selectivity control, current challenges, and future opportunities are also discussed.

Key words: boronate complexes, ring-strain-promoted transformations, catalytic asymmetric transformations
