Abstract

Transition-metal-catalyzed cycloisomerizations of enynes have recently been extensively studied. In particular, gold catalysts have been shown to be highly efficient in this type of reactions, which provide rapid and atom economical access to a variety of cyclic structural motifs.[1, 2] Previous investigations have demonstrated that the reaction pathway is highly substrate-dependent. In the absence of external nucleophiles, the alkene moiety usually ...
