Abstract
An efficient diastereoselective approach for the preparation of novel substituted pyridines has been developed through a one-pot, four-component reaction of easily available aromatic aldehydes, malononitrile, and 6,8-dimethyl-2-hydroxy-4H-pyrimido[1,2-a]pyrimidine-4-one, in appropriate alcohols at reflux in the presence of DIPEA (diisopropyl ethyl amine) as organic base catalyst. Unexpected products were obtained in high to excellent yields using a simple workup procedure. The product synthesized showed high diastereoselectivity in which its stereochemistry was confirmed by X-ray diffraction analysis.
