In organic synthesis, the synthetic methodology of using cyclopropanes for cycloadditions has witnessed significant progress over the past several years. A series of cyclopropane-related cycloaddition reactions via organic or metal-catalyzed/mediated pathways has been exploited in constructing cyclic frameworks such as polycycles, bridged-ring carbocycles, and heterocycles. Moreover, this synthetic chemistry has also recently blossomed in the pursuit of highly efficient asymmetric cycloadditions, C–H bond-activated cycloadditions, photoredox catalysis-cooperated cycloadditions, and several other unique reaction processes. Although numerous cyclopropane-based cycloaddition reactions have been reported, the newly explored cycloadditions have not yet been reviewed. Herein, we present recent progress in cyclopropane-related cycloadditions over the past 6 years.

在有机合成中，使用环丙烷进行环加成的合成方法在过去几年中取得了重大进展。通过有机或金属催化/介导的途径进行的一系列环丙烷相关的环加成反应已被用于构建环状骨架，例如多环，桥环碳环和杂环。此外，这种合成化学最近还发展为追求高效的不对称环加成反应，CH键活化的环加成反应，光氧化还原催化协同的环加成反应以及其他几种独特的反应过程。尽管已经报道了许多基于环丙烷的环加成反应，但尚未对新探索的环加成进行综述。在此处，
