Synthesis of Phenanthrene-based Polycycles by Gold (I)-Catalyzed Cyclization of Biphenyl Embedded Trienynes
Gold(I)-catalyzed cyclization of o-alkenyl-o?-alkynylbiaryls in the presence of external or internal nucleophiles provides a straightforward access to phenanthrene-based polycycles, which are of considerable interest in materials science. Thus, their reactions with alcohols yield functionalized dihy...

| Sumario: | Gold(I)-catalyzed cyclization of o-alkenyl-o?-alkynylbiaryls in the presence of external or internal nucleophiles provides a straightforward access to phenanthrene-based polycycles, which are of considerable interest in materials science. Thus, their reactions with alcohols yield functionalized dihydrophenanthrenes, in a process that can also be carried out intramolecularly, to provide phenanthrene-derived heteropolycyclic compounds. Moreover, benzo[b]triphenylenes can be synthesized from o-methoxyvinyl-o?-alkynylbiaryls, in a reaction in which an (hetero)aryl substituent at the triple bond acts as an internal nucleophile. |
