Abstract

This review highlights recent advances in the synthesis of (hetero)aromatic systems via cycloaddition reactions of alkynylmetals with dienes and dipoles. This methodology is advantageous when accessing complex molecules because it offers a short, atom-economic, and regioselective route to quickly access scaffolds of broad interest to the chemical sciences.
