Fjord-Stitching Strategy Enables Chiral Heteroatom-Doped Zigzag Hydrocarbon Belts! Herein, the synthesis of chiral heteroatom-embedded hydrocarbon belts via fjord-stitching CN coupling reactions of easily accessible resorcin[4]arene and resorcin[6]arene derivatives with diverse chiral amines is demonstrated.

Herein, the synthesis of diverse chiral O/N-doped zigzag hydrocarbon belts based on bridging of the fjords of resorcin[4]arene and resorcin[6]arene derivatives with chiral amines through palladium-catalyzed intermolecular CN bond formation reactions is reported. The resulting nanobelts exhibit unique chiral cavity structures and demonstrate intriguing chiroptical properties. Furthermore, a chiral transfer process from small molecule amines to the hydrocarbon nanobelts, offering new insights for designing and synthesizing novel chiral nanobelts is uncovered.
