A New Version of Multicomponent Synthesis of 4,6-Diaryl-2-sulfanylidene-1,2-dihydropyridine-3-carbonitrile Derivatives
摘要:
Multicomponent condensation of aromatic aldehydes with acetophenones, cyanothioacetamide, and alkylating agents has been shown to provide synthetic routes to various pyridine and thienopyridine derivatives. The structure of some of the synthesized heterocycles has been confirmed by X-ray analysis.
Synthesis of 4-aryl-6-phenyl-2-thioxo-1,2-dihydropyridine-3-carbonitriles by three-component condensation of aromatic aldehydes with cyanothioacetamide and 4,4,4-trifluoro-1-phenylbutane-1,3-dione
摘要:
4-Aryl-6-phenyl-2-thioxo-1,2-dihydropyridine-3-carbonitriles were synthesized by three-component condensation of aromatic aldehydes with cyanothioacetamide and 4,4,4-trifluoro-1-phenylbutane-1,3-dione. The reaction involved initial formation of Michael adducts which underwent acyl cleavage.
