Enantioselective Synthesis of Configurationally Stable 5helicenes Containing 1,2-Azaborine Units

Key Points

• This research aims to develop an efficient method for synthesizing BN-doped [5]helicenes with high enantioselectivity.
• Utilized a highly enantioselective, intramolecular, Au-catalyzed alkyne hydroarylation reaction.
• Synthesized two families of BN-doped [5]helicenes.
• Notable enantioselectivity achieved in the synthesis process.
• Two distinct families of helicenes were successfully produced.
