cascade reaction of δ‐aminoalkynes was developed for the synthesis of various eight‐membered nitrogen heterocycles in excellent yields. The reaction proceeds via a hydration of δ‐aminoalkynes and subsequent intramolecular cyclization and intermolecular addition as well as ring‐expansion cascade reaction with another electron‐deficient alkynes. This method has the advantages of simple operation and mild
