Abstract: A pot, atom and step economy (PASE) synthesis of new 5-C substituted 2,4-diamino-5H-chromeno[2,3-b]pyridine-3-carbonitriles was carried out. This process involves the one-pot, pseudo four-component reaction of salicylaldehydes, malononitrile, 1,3-cyclohexanediones and Et3N as a catalyst in acetonitrile at reflux. This novel one-pot reaction provides an effective and convenient way to 5-C cyclohexyl-functionalized chromeno[2,3-b]pyridines, which are promising compounds for different biomedical applications. The procedure utilizes readily available reagents, it is easily carried out and the work up is not complicated. 2,4-diamino-5-(2-hydroxy-6-oxocyclohex-1-en-1-yl)-5H-chromeno[2,3-b]pyridine-3-carbonitriles are crystallized directly from the reaction mixture and the isolation includes only filtration. Molecular docking studies of the synthesized 2,4-diamino-5H-chromeno[2,3-b]pyridine-3-carbonitriles were also carried out to elucidate their relationship with the binding pockets of the mitogen activated protein kinase (MK).
