Thiazole ring is an important five-membered aromatic heterocyclic ring, and its derivatives have various biological activities and are widely used in medicine. The synthesis of 2,5-diarylthiazole derivatives by acylation, thiolation, cyclization and Heck reaction using inexpensive and readily available substituted benzoic acid as raw materials was developed. The key point was to optimize the Heck reaction conditions and explore the possible reaction mechanism. The method has mild reaction conditions, simple operation, and good substrate universality, which provides a new direction for the synthesis of 2,5-diaryl substituted thiazoles.
Key words: 2,5-diarylthiazole, Heck reaction, organic synthesis
