Significance

Bis-acetylenic ketones are used for the efficient (88-91%) one-pot synthesis of triazepine and oxa-triazaindenone cores representing two unusual heterocycles. The reactions are convenient, high yielding, and modular; therefore, they could be useful tools for the rapid generation of families of complex, diverse, and dense heterocyclic building blocks.
