Abstract The preparation of the potential antimalarial agents 4,4′-bis(trifluoromethyl)stilbene, 4,4′-bis(trifluoromethyl)-α-phenylcinnamic acid, and several trifluoromethyl-bearing intermediates is described. Use of a modified Willgerodt synthesis provided the best synthetic route to 4-trifluoromethylphenylacetic acid. A modification of the Grignard synthesis of 4-trifluoromethylbenzaldehyde and 1-
摘要描述了潜在的抗疟药4,4'-双(三氟甲基)sti,4,4'-双(三氟甲基)-α-苯基肉桂酸以及几种含三氟甲基的中间体的制备。使用改良的Willgerodt合成方法可提供合成4-三氟甲基苯基乙酸的最佳途径。据报道,适合大规模制备的4-三氟甲基苯甲醛和1-(4-三氟甲基苯基)乙醇的格利雅合成法的改进。
