摘要

This paper describes the total synthesis of thelephantin G,thus revising the proposed structure 1 to 2. The key steps involved a double Suzuki-Miyaura coupling and an esterification reaction. By a similar strategy, ganbajunins D and E (3 and 4) were also prepared. Compound 2 strongly inhibited TNF (tumor necrosis factor)-R production in rat basophilic leukemia (RBL-2H3) cells: IC50 ) 3.5 nM, while a mixture of 1 and its regioisomer 15 showed no such activity.
