模拟四氢叶酸辅酶一碳单元转移反应,通过其甲酸氧化态模型化合物苯并咪唑盐与一碳单元的受体Grignard试剂的加成-水解反应,为正戊醛的合成提出了一种仿生合成新方法,并对其反应机理和条件进行了讨论。
Based on the one-carbon unit transfer reaction of tetrahydrofolate coenzymes,n-pentanal was synthesized successfully by using benzoimidazolium salt as the tetrahydrofolate coenzyme model at the formic acid oxidation level and the Grignard reagent as a nucleophile to which one carbon unit was transferred.Herewith the novel method for the preparation of n-pentanal was proposed.The condition for the synthesis of n-pentanal was studied and its reaction mechanism was discussed.
