  Synthesis of Fused 2Н-Pyridin-2-ones under the Conditions of Multicomponent Hantzsch Reaction

  摘要：

  One-pot process was studied between a substituted 4-hydroxy-2H-pyran-2-one and aromatic aldehydes and ammonium acetate in the conditions of modified Hantzsch reaction in acid environment under thermal and microwave activation. Arylmethylenebis-4-hydroxy-2H-pyridin-2-ones, hydrochromenopyridinone, and their oxygen-containing heteroanalogs were isolated. A primary condensation was confirmed into bispyran-2-one adducts, and at the use of salicilaldehyde, into pyranochromene with subsequent recyclization of pyranone fragments in pyridinone ones.
