AbstractWe report here a novel and facile method for the synthesis of (±)-4(5)-[1-(2,3-dimethylphenyl)ethyl]-1H-imidazole (medetomidine) in a good yield in five steps. The method involves Wittig olefination of the phenylimidazolylketones, followed by a hydrogenation. We demonstrate that the Wittig alkenylation reaction provides a convenient step for the synthesis of medetomidine without requiring methylation
摘要我们在这里报告了一种新颖且简便的方法,可分五步以高收率合成(±)-4(5)-[1-(2,3-二甲基苯基)乙基] -1 H-咪唑(美托咪定)。该方法包括将苯基咪唑基酮的维蒂希烯化,然后氢化。我们证明,Wittig烯基化反应为美托咪定的合成提供了一个方便的步骤,而无需甲基化和脱水步骤,这是先前方法中存在问题的过程。 图形概要合成美托咪定的新途径。
