AbstractA mild and efficient protocol for the synthesis of 2‐amino‐5‐arylidene‐1,3‐thiazol‐4(5H)‐ones is reported by three component reaction of aldehydes, rhodanine and secondary amines in the presence of magnesium oxide nanoparticles as heterogeneous nanocatalyst in good yields and short reaction times.

A new methodology has been developed towards the room temperature synthesis of novel 2-amino-5-alkylidenethiazol-4-ones from aldehydes, amines and rhodanine in one-pot. A heterogeneous dipolar catalyst has been utilized for this reaction. The unique properties of this catalyst effectively synthesize such compounds at room temperature in contrast to all earlier reports. (C) 2011 Elsevier Ltd. All rights reserved.
