摘要：

A potpourri of remarkable reactions is initiated by the AuCl 3-catalyzed cyclization of an ortho-alkynyl benzaldehyde. In the presence of an olefin or an electron-rich heteroarene as a dienophile or nucleophile, this cyclization provides selective access to a broad variety of polycyclic structures (see scheme).
