(±)-Faranal was synthesised by a convergent route involving 1,4-cis-hydrogenation of two properly substituted conjugated diene building blocks to introduce stereospecifically the 6(E) and 10(Z) double bonds of the final target molecule. meso-2,3-Dimethylsuccinic acid was used to prepare a building block for the ‘right-hand’ part of faranal carrying two vicinal erythro-configured methyl groups.
(±)-法拉纳尔是通过一种汇聚路线合成的,该路线涉及对两个适当取代的共轭二烯构建块进行1,4-顺式氢化,以立体特异性地引入最终目标分子的6(E)和10(Z)双键。用内消旋-2,3-二甲基丁二酸制备了一个构建块,用于携带两个邻位赤型配置的甲基的法拉纳尔的右手部分。
