Formation of Multiple Naturally Occurring Meroterpenoid Scaffolds by the Norrish‐Yang Reaction of a <i>p</i> ‐Benzoquinone

Abstract The Norrish‐Yang reaction, as a typical example, demonstrates the inherent ability of photochemical reaction to facilitate formation of sterically congested C−C bonds, efficiently crafting intricate ring structure in complex organic molecules. Herein we report for the first time a unified synthesis using quinone‐based acid‐promoted Norrish‐Yang photocyclization for the stereoselective construction of multiple avarane‐type meroterpenoid natural products.
