title = "Enantioselective Synthesis of Sulfur-Containing Medium-Ring Heterocycles with Axial Chiralities by Catalytic Intramolecular [2+2+2] Cycloaddition",
abstract = "The rhodium-catalyzed enantioselective intramolecular cycloaddition of triynes connected by sulfur-containing tethers gave tribenzothiepins and a tribenzodithiocin in high yields with good-to-excellent enantiomeric excesses. The present protocol generated axial chiralities fused with medium-ring heterocycles. In particular, this is the first example of the catalytic and highly enantioselective construction of a tribenzodiheterocin skeleton.",
