Approach to the Synthesis of Briarane Diterpenes through a Dianionic Claisen Rearrangement and Ring-Closing Metathesis

Crimmins, Michael T.,Zhang, Yan,Williams, Philip S.

, p. 3907 - 3910 (2017)

The synthesis of the briarane-brianthein A core has been accomplished utilizing an extension of the dianionic Ireland-Claisen rearrangement to establish the C1 quaternary carbon and the adjacent C10 ring juncture stereocenters. Two sequential ring-closing metathesis reactions were exploited to construct the 6-10 trans fused ring system.
