Piperazine-Amberlyst®15-catalysed synthesis of 2-amino-4H-chromenes, chromeno[2,3-b]pyridines and chromeno[2,3-d]pyrimidines
Chromenes, biologically-active scaffolds, and their variants have been often synthesized by the combination of salicylaldehyde, malononitrile, and nucleophilic species (indoles, naphthols, nitro compounds, thiols). Whereas this combination furnishes specifically 2-amino-4H-chromenes, other related c...
