Abstract

Base-mediated cascade reactions of α,β-unsaturated ketones and 1,1-enediamines, which include Michael addition, intramolecular cyclization, aromatization, and a base-dependent optional loss of HNO2, provide 2-amino-4,6-diarylpyridine derivatives. The methods are suitable for efficient parallel synthesis of pyridines.
