Abstract

One-pot multi-component synthesis of 2-amino-3,5-dicarbonitrile-6-thio-pyridines derivatives using WEB (water extract of banana peels ash) as a green catalyst is described. A variety of aromatic aldehydes (with electron-donating and electron-withdrawing groups) in conjunction with aromatic and aliphatic thiols are known to tolerate this reaction condition using WEB. The reaction has simple work up procedure without using toxic solvents.
