  Total Syntheses of Cannabicyclol, Clusiacyclol A and B, Iso-Eriobrucinol A and B, and Eriobrucinol

  摘要：

  Total syntheses of a series of chromane natural products that contain a cyclobutane ring are described. A unified theme In the strategy employed for all these syntheses Is an oxa-[3 + 3] annulation for constructing the chromane nucleus and a stepwise cationic [2 + 2] cycloaddition for the cyclobutane formation. More Importantly, the two reactions could be rendered in tandem, thereby providing an expeditious approach to this family of natural products.

  Betuphenone F, a natural product isolated from the bark of Betula alnoides Ham. ex D. Don, has the potential to be a new-generation anti-cancer agents based on anti-austerity. We succeeded in constructing the 2-oxabicyclo[3.3.1]nonane skeleton, a structural feature of betuphenone F, and achieved the first total synthesis of rac-bethuphenone F from phloroglucinol in three steps.
