Asymmetric Synthesis of Axially Chiral Olefins and Heterobiaryls via Rhodium-Catalyzed C-C Activation and [4 + 2] Annulation
{{output}}
Axially chiral biaryls are privileged scaffolds in chiral ligands, catalysts, and functional molecules. Reported herein is rhodium-catalyzed atroposelective [4 + 2] annulation of benzocyclobutenols with alkynes. The coupling system is chemodivergent under silv... ...
