A Concise Bioinspired Semisynthesis of Rumphellaones A–C and Their C-8 Epimers from β-Caryophyllene. J. Nat. Prod. 2020, doi: 10.1021/acs.jnatprod.0c00403
This is the first semisynthetic route toward rumphellaones B and C and their C-8 epimers as well as the shortest synthesis of rumphellaone A and its C-8 epimer from the most accessible sesquiterpene, β-caryophyllene.
