介绍了从 4-烷氧基-1,1,1-三氟-3-烯烃-2 反应合成一系列 1-叔丁基-3(5)-(三氟甲基)-1H-吡唑的研究-ones [CF3C(O)CH=C(R1)(OR),其中 R = Et 且 R1 = H 或 R = Me 且 R1 = Me、Ph、4-Me-C6H4、4-MeO-C6H4、4- F-C6H4、4-Cl-C6H4、4-Br-C6H4、4-I-C6H4、fur-2-yl、thien-2-yl或naphth-2-yl]与叔丁基肼盐酸盐。当[BMIM][BF4](1-丁基-3-甲基咪唑四氟硼酸盐)和吡啶用作反应介质时,我们得到了1-叔丁基-3(5)-三氟甲基吡唑的混合物。当反应在乙醇中的 NaOH 中进行时,会形成具有高区域选择性的 5-三氟甲基-1-叔丁基-1H-吡唑。4-烷氧基-1,1水解后,生成1-叔丁基-3-三氟甲基-1H-吡唑,
This disclosure relates to substituted urea eIF2α kinase activators including methods of making and using the same. For example, such activators can include cycloalkyl aryl ureas, which activate at least one eIF2α kinase. These compounds may be useful for treatment of diseases such as, for example, cancer, hemolytic anemia not caused by infectious agents, Wolcott-Rallison syndrome, neurodegenerative disease, tuberous sclerosis complex, fragile-X syndrome, autism spectrum disorder, and ribosomal defect disease.
