(S)-4,4-Dichloro-3-methylbutanoic acid was prepared in 51% overall yield from commercially available starting materials using an organocatalytic transfer hydrogenation to 4,4-dichloro-3-methylbut-2-enal in the key step. The (S)-dichloro acid was used as an intermediate in the first total synthesis of dysideaproline E and a diastereomer confirming the structure of the natural product.
(S)-4,4-二氯-3-甲基丁酸的合成采用了商业可得的起始材料,通过有机催化转移氢化反应,以51%的总体产率制备而成,关键步骤为4,4-二氯-3-甲基丁-2-烯醛。该(S)-二氯酸被用作第一个全面合成Dysideaproline E的中间体,以及确认天然产物结构的一个立体异构体。
