    This work describes the optimization process for the synthesis of β-trifluoromethylated ketones from trifluoromethylated allylic alcohols. This transformation proceeds through a ruthenium catalyzed isomerization under mild conditions with high atom economy. The effect of the CF3 group was analyzed and it provides fundamental insights into the isomerization reaction.

    As part of a search for biologically active analogues of vitamin E, fluorine derivatives of tocotrienol and related compounds were synthesized by the ring-closure of trifluoroprenols with trimethylhydroquinone. For this purpose, the trifluoroprenols were synthesized by the Wittitg-Horner reaction of trifluoroacetone or its prenyl homologues with triethylphosphonoacetate followed by reduction of the trifluoromethylated acrylic ester derivatives. Although 4, 4, 4-trifluoroprenol itself did not react with the hydroquinone, 7, 7, 7-trifluorodiprenol and higher prenols gave 6-chromanols with a trifluofomethylated side-chan.

    As the extension of our research to find a biologically active analogue of vitamin E, a more convenient method for the synthesis of fluorine derivatives of 6-chromanol than our previous method was developed. Thus, 2-(3-chloropropyl)-2, 5, 7, 8-tetramethyl-6-chromanol (3) was synthesized by the reaction of 6-chloro-3-methyl-2-hexen-1-ol (2) and trimethylhydroquinone, and the phosphonium ylides (5 and 6) derived from 3 were condensed with trifluoromethylated ketones to give 2-(trifluoroprenyl)-6-chromanol compounds (1a, 1b and 1c) by means of the Wittig reaction as modified by Schlosser. By the use of this revised procedure, the total yields of the chromanols were much improved. Further, the modified Wittig reaction showed higher stereoselectivity than the previous syntheses of these compounds. The double bonds of the side-chain of the products were reduced to give fluorine derivatives of tocopherol analogues. Compound 3 was found to be a useful intermediate for the facile synthesis of vitamin E derivatives.
    作为我们寻找维生素 E 生物活性类似物研究的延伸,开发了一种比我们之前的方法更方便的 6-苯并二氢喃醇生物的合成方法。因此,通过6--3-甲基-2-己烯-1-醇(2)的反应合成2-(3-丙基)-2,5,7,8-四甲基-6-苯并二氢喃醇(3)和三甲基氢醌,以及由3衍生的叶立德(5和6)与三甲基化酮缩合,通过Schlosser改进的Wittig反应得到2-(三异戊二烯基)-6-苯并二氢喃醇化合物(1a、1b和1c)。通过使用这一修改后的程序,苯并二氢喃醇的总产率得到了很大提高。此外,改进的维蒂希反应比以前合成的这些化合物显示出更高的立体选择性。产物侧链双键被还原,得到生育酚类似物的生物。化合物 3 被发现是一种有用的中间体,可用于轻松合成维生素 E 衍生物
