Recent Advances in Metal‐Catalyzed Decarboxylative Reactions of Vinyl Benzoxazinanones

Vinyl benzoxazinanones as versatile building blocks can undergo transition‐metal‐catalyzed decarboxylation to enable various kinds of interesting transformations by various [4+n], transition‐metal‐catalyzed C−H allylation of arenes and other types of annulations. Herein, we reviewed the latest research progress in the research and application of vinyl benzoxazinones in metal‐catalyzed decarboxylative reactions to illustrate their synthetic value.
