Abstract
AbstractConsecutive thermal and metal‐catalyzed dehydro‐Diels–Alder (DDA) reactions of sulfur‐tethered tetraynes, possessing a 1,3‐diyne moiety, proceeded efficiently, and axial chirality was achieved for the resulting dibenzothiophenyl moieties. Chiral‐rhodium catalysis realized a highly enantioselective synthesis, and transformations into bis(benzocarbazole) derivatives were also achieved.
