Transition metals in organic synthesis. Part 85. A general approach to 1,6-dioxygenated carbazole alkaloids; first total synthesis of clausine G, clausine I, and clausine Z.
[摘要]:Using the palladium-catalyzed construction of the carbazole framework, a highly efficient route to 1,6-dioxygenated carbazole alkaloids was developed and applied to the total synthesis of clausenine, 6-methoxymurrayanine, clausenol, clausine G, clausine I, and clausine Z. The three latter natural products were synthesized for the first time.
