摘要：

A one-pot three-component condensation of all aldehyde, malononitrile, and thiophenol has been achieved by conventional and ultrasound method The reaction has been catalyzed by boric acid in aqueous medium This protocol afforded corresponding 2-amino-3,5-dicarbonitrile-6-thio-pyridines in shorter reaction times and high yields with the green aspects by avoiding toxic catalysts and solvents.
