  Synthesis and structure–activity relationships of 5-phenylthiophenecarboxylic acid derivatives as antirheumatic agents

  摘要：

  5-(Phenylthiophene)-3-carboxylic acid (2a), a metabolite of esonarimod (1), which was developed as a new antirheumatic drug, was considered as a lead compound for new antirheumatic drugs. A new series of 2a derivatives were synthesized and their characteristic pharmacological effects, that is their antagonistic effect toward interleukin (IL)-1 in mice and the suppressive effect against adjuvant-induced arthritis (AIA) in rats, were evaluated and compared with those of 1. The structure-activity relationships indicated that [5-(4-bromophenyl)- thiophen-3-yl]acetic acid (5d), methyl [5-(4-chlorophenyl)-thiophen-3-yl]acetate acid (5d), and methyl [5-(4-bromophenyl)-thiophen-3-yl]acetate (5i) suppressed AIA more potently than 1 and all of the other synthesized compounds.

  The invention relates to a method for decarboxylating C—C bond formation by reacting carboxylic salts with carbon electrophiles in the presence of transition metal compounds as catalysts. The method represents a decarboxylating C—C bond formation of carboxylic acid salts with carbon electrophiles, wherein the catalyst contains two transition metals and/or transition metal compounds, from which one is present, preferably, in the oxidation step, which are different from each other by one unit, and catalyzes a radical decarboxylation which is absorbed during the second oxidation steps, which are different from each other by two units and catalyzes the two electron processes of a C—C bond formation reaction.

  Suzuki–Miyaura coupling of heteroaryls is an important method for the preparation of compound libraries for medicinal chemistry and materials research. Although many catalysts have been developed, none of them have been generally applicable to the coupling reactions of heteroaryl chlorides and tosylates at room temperature. We discovered that a catalyst combination of Pd(OAc)2 and XPhos (2-dicyclohexylphosphanyl-2′

  杂芳基的 Suzuki-Miyaura 偶联是制备用于药物化学和材料研究的化合物库的重要方法。尽管已经开发了许多催化剂，但它们都没有普遍适用于杂芳基氯与甲苯磺酸酯在室温下的偶联反应。我们发现 Pd(OAc)2 和 XPhos（2-二环己基膦酰基-2',4',6'-三异丙基联苯）的催化剂组合可以有效地催化这些偶联。除了催化剂的选择，在含水醇溶剂中使用氢氧化物碱对于快速偶联也是必不可少的。这些条件促进了活性催化剂（XPhos）Pd0 的快速释放，并加速了催化循环中的金属转移。大多数杂芳基氯（31 个实例）和甲苯磺酸盐（17 个实例）的主要家族在室温下在几分钟到几小时内达到完全转化。该方法可以很容易地扩大规模以进行克级合成。此外，我们检查了整个反应中偶联伙伴的相对反应性。富电子杂芳基氯化物和甲苯磺酸盐的反应速度比缺电子杂芳基化合物慢，顺序为吲哚、吡咯呋喃、噻吩>吡啶。类似地，缺电子芳基硼酸的反应
