spongiform encephalopathies (TSEs) or priondiseases are a family of invariably fatal neurodegenerative disorders, and there are no effective therapeutics currently available. In this paper, we report on the design, synthesis, and screening of a series of pyridine dicarbonitriles as potential novel priondiseasetherapeutics. A virtual reaction-based library of 1050 compounds was constructed. Docking and evaluation
pot, three component synthesis of 2-amino-4-aryl-3,5-dicyano-6-sulfanylpyridines and the corresponding 1,4-dihydropyridines are from readily accessible starting materials is described. Simply heating of an ethanolic solution of structurally diverse aldehydes with various thiols and malononitrile in the presence of nanocrystalline magnesium oxide provides the highly substituted pyridine derivatives

A basicionicliquid, [bmIm]OH, efficiently promotes a one-pot, three-component condensation of aldehydes, malononitrile, and thiophenols to produce highly substituted pyridines in high yields at room temperature. This reaction does not involve any hazardous organic solvent and toxic catalyst. The ionicliquid is recovered and recycled for subsequent reactions.
Three‐component coupling of aldehydes, malononitrile, and thiophenols has efficiently been carried out at room temperature using potassium fluoride on alumina (KF·Al2O3) as a catalyst to furnish highly substitutedpyridines in high yields. J. Heterocyclic Chem., (2009).
