Abstract:
Rh‐catalyzed enantioselective intramolecular reactions of triynes consisting of 1,6‐diyne and 1,10‐diyne moieties tethered by sulfur or oxygen and ortho‐ phenylene moieties proceeded to give chiral tetrabenzoheteronines possessing a nine‐membered ring system as [2+2+2] cycloadducts. In the reaction of triynes consisting of 1,6‐diyne and 1,11‐diyne moieties, sulfur‐tethered substrates gave chiral metacyclophanes with an eleven‐membered ring system, whereas an oxygen‐ and sulfur‐tethered substrate afforded a tetrabenzo‐1,4‐oxathiecine with a ten‐membered ring system. The mechanisms of the different reaction pathways depending on the heteroatom of the tether are discussed.
