This invention relates to the use of a group of aryl ureas in treating cytokine mediated diseases, other than cancer and proteolytic enzyme mediated diseases, other than cancer, and pharmaceutical compositions for use in such therapy.
Copper-catalyzed C-C couplingreaction of aryl iodides with diethylmalonate in toluene at 90 °C gave arylated malonates using 5 mol% of CuI with hydrazone la as a ligand in good yields under an aerobic atmosphere. We also found Cul/hydrazone 1b in toluene to be an efficient catalytic system for C-O couplingreactions of aryl bromides with phenols to give aryl ethers in good yields at 110 °C under an
在 90°C 下,芳基碘化物与丙二酸二乙酯在甲苯中的铜催化 CC 偶联反应得到芳基化丙二酸酯,使用 5 mol% 的 CuI 和腙 1a 作为配体,在有氧气氛下以良好的收率。我们还发现甲苯中的 Cul/腙 1b 是一种有效的催化体系,用于芳基溴化物与苯酚的 CO 偶联反应,在 110 °C 有氧气氛下以良好的产率得到芳基醚。
