Dibenzoylmethane in the Synthesis of Selenium-Containing Di- and Tetrahydropyridine-3-carbonitriles

Key Points

• The research aims to synthesize selenium-containing di- and tetrahydropyridine-3-carbonitriles using dibenzoylmethane.
• Combined cyanoselenoacetamide, 2-furan- or 2-thiophenocarbaldehydes, and dibenzoylmethane in ethanol.
• Utilized excess piperidine or morpholine under argon atmosphere.
• Characterized the resulting compounds through X-ray diffraction analysis.
• Obtained 6-hydroxy-3-cyano-1,4,5,6-tetrahydropyridine-2-ammonium selenolates.
• Synthesized 2-alkylselenodi- and tetrahydropyridine-3-carbonitriles.
• Confirmed the structure of new compounds via X-ray diffraction.
