, p. 4755 - 4759 (2005)
An improved, convergent synthesis of CB92834 is relying on a Suzuki cross-coupling reaction and easily allows multigram-scale preparation of the compound. The approach features three highly stereoselective steps.

Quaternary stereocenters that bear a sulfur substituent can be created with nearly perfect stereocontrol through an intramolecular Michael-type process. Lewis acids (L.A.) accelerate the intramolecular sulfur-atom transfer from the oxazolidine-2-thione functionality to the β carbon atom of the β,β-disubstituted enoyl moiety, whereas the chirality of the oxazolidine-2-thione portion controls reaction stereochemistry (see scheme).
