An Efficient Synthesis of Fused 3-Formylpyridines and 5-Formylpyrimidines

Cyclization of 2-dimethylaminomethylene-1,3-bis(dimethylimonio)propane diperchlorate with various amino heterocycles led to the formation of a series of fused heterocyclic systems containing a 3-formylpyridine or 5-formylpyrimidine unit.
