(2S,3S)-1-Phenylthio-2,3-pentanediol (2) and 2S,3S)-1-phenylsulfonyl-2,3-pentanediol (16) were prepared by reducing the corresponding diketones, 6 and 15, with baker's yeast. Conversion of 2 to (3S,4R)-8-nonene-3,4-diol (13), the key intermediate for the synthesis of (+)-endo-brevicomin [endo -7-ethyl-5-methyl-6,8-dioxabicyclo[3.2.1]octane, (1R,5S,7S) -1], is also described.
(2S,3S)-1-苯基硫代-2,3-戊二醇 (2) 和 (2S,3S)-1-苯基磺酰基-2,3-戊二醇 (16) 是通过用酵母还原相应的二酮 6 和 15 制备的。将 2 转化为 (3S,4R)-8-壬烯-3,4-二醇 (13),这是合成 (+)-内源-美迪可明 [内源-7-乙基-5-甲基-6,8-二氧杂双环[3.2.1]八烷, (1R,5S,7S)-1] 的关键中间体,亦有描述。
