A simple sequential one-pot synthesis of 4-aryl thiazole-based Schiff bases

Thiazole based Schiff base scaffolds in recent years have become the integral part of the drug development. These scaffolds are gaining much importance due to their widespread uses as versatile building blocks for the construction of lead drug molecules. Their excellent biological activities have encouraged us to prepare newer compounds with aryl group in the fourth position of thiazoles incorporating azomethine linkages. The strategies so far reported to obtain 4-aryl thiazoles are time consuming, tedious, and costly. In this context, we report a facile one pot synthetic method to obtain novel 4-aryl thiazoles with excellent yield (83-98%), lesser reaction time (40 min) and under milder conditions with no catalyst and no purification techniques.
