A one‐pot reaction was developed efficiently by AuCl3 catalyzed intramolecularcyclization of aromatic o‐alkynyloximes and 2‐alkynylcycloalkene‐1‐carbaldoximes leading to the formation of isoquinoline and pyridine derivatives with high yields. This methodology has been applied for aromatic as well as aliphatic systems. Aromatic o‐alkynyloximes are benzene and naphthalene, whereas electron‐donating
