Oh my goch : The total syntheses of ainsliadimer B and gochnatiolides A and B from α‐santonin have been accomplished in 25 steps with approximately 1 % overall yield. A Diels–Alder reaction of natural dehydrozaluzanin C with a monomeric guaianolide derivative allows stereoselective assembly of a dimeric gochnatiolide‐type skeleton with the required stereochemistry and preinstalled functionalities for the synthesis of dimeric ainsliadimer B and gochnatiolides A and B (see scheme).
