Artatrovirenols A and B are two natural sesquiterpenoids with a complex tetracyclic backbone, and their chemical total synthesis is challenging. Here, the authors report a concise synthesis of artatrovirenols A and B in 9 and 8 steps, respectively, featuring a bioinspired [4 + 2] cycloaddition reaction to construct the tetracyclic core.
