Recent Progress in the Synthesis of Sesquiterpenoid Involving Spirocyclic Carbon Framework

Spirocarbocyclic natural products have been attracting considerable attention from synthetic organic chemists. This review focused on total syntheses of sesquiterpenoids involving spiro[4.5]decane and spiro[5.5]undecane scaffolds, compiling syntheses of colletoic acid, cubebol, axenol, vetispirene, hinesol, agarospirol, axenol, gleenol, exiguamide, exigurin, erythrodiene, spirojatamol, antroalbocin A, omphalic acid, dactylone, and aplydactonee since 2015.
