A new synthetic route to afford 2-amino-5-aryl thiazoles has been developed. The starting aminothiazole derivative can be arylated at position 5 with aryl iodides under palladium-catalyzed conditions. Mechanistic studies suggest a proton-abstraction pathway for this transformation.
一种新的合成路线已被开发,用于制备2-氨基-5-芳基噻唑。起始的氨基噻唑衍生物可以在钯催化条件下与芳基碘化物在5位进行芳基化。机理研究表明,该转化过程采用质子抽提途径。
