Highly substituted imidazo[2,1-b][1,3,4]thiadiazole derivatives were synthesized through successive cyclization and Suzuki-Miyaura cross-coupling reactions. The palladium-catalyzed coupling reaction was optimized and a wide range of boronic acids was used to evaluate the scope and limitations of the methodology. The final compounds were obtained in fair to very good yields and high compatibility with various chemical functions or (hetero)cycles was observed. Copyright
