Diastereoselective Synthesis of Double Axially Chiral Indole Derivatives via Friedel-Crafts Biarylation
{{output}}
We report a copper-catalyzed Friedel-Crafts biarylation protocol that delivers C3-site-selective doubly axially chiral biaryl indoles using five-membered cyclic diaryliodonium salts as biarylating agents. This atom-economical and highly diastereoselective prot... ...
