A new three-component condensation of β-ketonitriles, 4-fluorobenzaldehyde, and secondary cyclic amines was developed. A possible reaction mechanism has been proposed including Knoevenagel condensation followed by aromatic nucleophilic substitution.

Abstract Reaction of 3-formylchromone with cyclic secondary amines in methanol results in (E)-2-methoxy-3-(R2N-methylene)chroman-4-ones, while use of ethanol leads to (E)-2-morpholino-3-(morpholinomethylene)chroman-4-one or enaminoketones as dihydr

Three-component condensation of in situ generated pyridinium aroylmethylides with isatins or aromatic aldehydes and cyclic 1,3-dicarbonyl compounds gave a series of condensed 2-aroyl-2,3-dihydrofurans. The reaction proceeds diastereoselectively and r

When 2-(1-arylethylidene)malononitriles act upon 3-nitrobenzofurans in the presence of triethylamine, the furan ring opens and triethylammonium 2-aryl-1,1-dicyano-5-nitropenta-2,4-dien-1-ides are formed. The obtained salts containing the chromophoric
