متن کاملUnexpected one pot pseudo four-component reaction for the synthesis of (10E)-N-benzylidene-2-phenylH-imidazo [1,2-a]pyridin-3-amine derivatives under solvent-free conditions
This work described an efficient Pseudo four-component synthesis of (10E)-N-benzylidene-2-phenylH-imidazo[1,2-a]pyridin-3-amine derivatives from 2-aminopyridin, malononitrile and arylaldehydes in the presence of NaOH under solvent-free and conventional heating condition in good to excellent yields. A wide range of aromatic aldehydes would easily undergo condensations with 2-aminopyridin and mal...
