| Abstract: | The dearomatization reaction of heterocyclic compounds serves as a pivotal strategy for constructing complex cyclic frameworks, demonstrating significant application potential in pharmaceutical chemistry and functional materials science. Particularly, the dearomatization-enabled [3+2] cycloaddition strategy has emerged as a research hotspot for efficiently building multi-substituted heterocyclic architectures, owing to its inherent advantages of high atom economy and synthetic step-efficiency. This review systematically summarizes recent important advances in this field, with a particular focus on the applicability of novel catalytic systems—including transition-metal catalysis and organocatalysis—to representative heterocyclic substrates such as indoles, pyrroles, furans, and quinolines. It places special emphasis on analyzing the effects of catalyst structure, ligand effects, solvents, and additives on reaction selectivity, encompassing chemoselectivity, regioselectivity, and stereoselectivity, and also summarizes the breakthrough achievements recently made in asymmetric dearomative [3+2] cycloadditions. Looking forward, the development of novel activation modes, precise regulation of electronic effects aided by theoretical calculations, design of multicomponent cascade reactions, and the integration of artificial intelligence to accelerate catalyst screening and condition optimization will represent key directions for future breakthroughs. These efforts are expected to promote the practical application of this strategy in the total synthesis of natural products and the creation of high‑value‑added functional molecules. |
