The novel method for synthesis of fused heterocycles with an exocyclic methylene was investigated.The terminally acetylene-substituted heterocycles 3a-c and 6a-d were converted to the fused heterocycles with an exocyclic methylene 4a-c and 7a-d by intramolecular nucleophilic amination to acetylene part.
