Enantioselective Convergent Synthesis of Heterohelicenes via Copper-Catalyzed Propargylic Annulation/Acid-Promoted Aromatization

Abstract Heterohelicenes combine helical chirality with tunable electronic properties, making them attractive for applications in chiral materials and optoelectronics. However, their enantioselective synthesis, particularly for five-membered heterohelicenes, remains a long-standi...
