In conclusion, we have developed one pot multicomponent protocol
for the synthesis of highly functionalized pyridines using
aldehydes, malononitrile and thiophenol in the presence of sodium
chloride as a readily available reaction accelerator. Utilization of
NaCl in aqueous solvent system is proved as a green reaction medium
for carrying out organic transformations. Developed synthetic
method has several advantages such as wide scope of substrate,
easily available catalyst, operational simplicity, easy work up procedure
and higher product yields.
