The most recent advances in the construction of oxygen heterocycles by the directing-group-assisted transition-metal-catalyzed direct oxidative annulation of arenes with diverse alkynes are summarized in this review. More than 140 recent research papers and many closely related reviews are referenced in this paper. Nine different oxygen heterocycles frameworks are discussed. Several traditional transition-metal catalysts as well as some classical non-noble metals are utilized to promote the annulation. Three plausible controlling models are disclosed to clarify the excellent regioselectivity outcomes achieved in case of unsymmetrical alkyne substrates.1 Introduction2 Coumarins3 Isocoumarins and Their Analogues4 2-Pyrones and Their Analogues5 Chromones and Chroman-4-ones6 Chromenes and Isochromenes7 Fused Polycyclic Oxygen Heteroaromatics8 Benzofurans, Dihydrobenzofurans, and Furans9 Phthalides and Benzofuranones10 Benzoxepines11 Conclusion

定向基团辅助过渡金属催化芳烃与炔烃的直接 C-H 氧化环化用于简便构建各种氧杂环

本综述总结了通过定向基团辅助过渡金属催化芳烃与多种炔烃的直接氧化环化构建氧杂环的最新进展。本文引用了 140 多篇近期研究论文和许多密切相关的评论。讨论了九种不同的氧杂环骨架。几种传统的过渡金属催化剂以及一些经典的非贵金属被用来促进环化。公开了三种似是而非的控制模型，以阐明在不对称炔烃底物的情况下实现的出色区域选择性结果。
