Enantioselective Synthesis of Dithia[5]helicenes and their Postsynthetic Functionalization to Access Dithia[9]helicenes

A highly enantioselective synthesis of 5,13‐disubstituted dibenzo[d,d′]benzo[1,2‐b:4,3‐b′]dithiophenes is reported. Key for the successful assembly of these helical architectures is the last two successive Au‐catalyzed intramolecular alkyne hydroarylation events. Specifically, the second cyclization...
