containing ca. 87% of the (2S)-isomer (3), which is converted into (3R,7R)-3,7,11-trimethyldodecan-1-ol (8), a key intermediate in the synthesis of natural α-tocopherol (19); the same alcohol (8) and its lower homologue (16), which is also an intermediate in the same synthesis, are both obtained in optically pure form from the acid (9).
通过面包酵母还原醛(1),得到2-甲基-5-苯基五-4-烯-1-醇,其含有约1 。(2 S)-异构体(3)的87%转化为(3 R,7 R)-3,7,11-三甲基十二烷-1-醇(8),这是合成天然α的关键中间体-生育酚(19); 相同的醇(8)和它的低级同系物(16),它们也是同一合成中的中间体,都是从酸(9)以光学纯的形式获得的。
