An efficient synthesis of 2-4-[(4-[4-(4-methoxyphenyl)piperazin-1-yl]methyl}-2-[4-(trifluoromethyl)phenyl]-1,3-thiazol-5-yl}methyl)thio]phenoxy}-2-methylpropanoic acid (1), a potent PPARpan agonist, is described. The seven-step synthesis, which afforded 1 in 30% overall yield, includes a highly regioselective carbon−sulfur bond formation via coupling of a bishydroxymethylthiazole (3) with 4-hydroxythiophenol
有效合成2- 4-[(4-[4-(4-甲氧基苯基)哌嗪-1-基]甲基} -2- [4-(三氟甲基)苯基] -1,3-噻唑-5描述了有效的PPARpan激动剂-基}甲基)硫代]苯氧基} -2-甲基丙酸(1)。七步合成,得到1在30%的总收率,包括经由bishydroxymethylthiazole(的耦合高度选择性碳-硫键形成3通过涉及三步伸缩序列)与4-羟基苯硫酚,剩余的醇的位移甲磺酸芳基酯的有效裂解,以及引入异丁酸片段的高效实用方法。
