A general method for the synthesis of 2,4,5-trisubstituted thiazoles has been developed. Starting from commercially available 2-bromothiazole, successive metalations using TMPMgCl·LiCl or TMP2Zn·2MgCl2·2LiCl lead to the corresponding magnesated or zincated thiazoles which readily react with various electrophiles providing highly functionalized thiazoles.
已经开发了合成2,4,5-三取代的噻唑的通用方法。从可商购的2-溴噻唑开始,使用TMPMgCl·LiCl或TMP 2 Zn·2MgCl 2 ·2LiCl进行连续的金属化反应会生成相应的镁化或锌化的噻唑,它们容易与各种亲电子试剂反应,从而提供高度官能化的噻唑。
