摘要
A formal total synthesis of iridoid 9-deoxygelsemide has been accomplished. Our approach features the use of (S)-carvone as starting material, Favorskii rearrangement to construct the functionalized cyclopentane core, Chugeav elimination to introduce the endocyclic double bond, and the ring-opening reaction of epoxide to build the second five-membered ring.
