RESUMO
[reaction: see text] A new and novel Au-catalyzed cycloisomerization of ynals bearing a pendant unsaturated bond leading to synthetically valuable [6.7.n]-tricyclic compounds were developed. This study strongly supports the intermediacy of [3 + 2] cycloaddition proposed by DFT calculation and provides an easy access to key skeletons found in a variety of natural products.

RESUMO
The Pd-catalyzed reaction of unsymmetrical alkynes with organoboronic acids gave a mixture of products and, whose ratios were controlled by the electronic as well as steric effects of the substrates.
