[reaction: see text] Chiral bidentate silyl reagents have been developed for the GC analysis of aliphatic 1,3- and 1,4-diols. These reagents react with the diols to cyclic siloxanes, which allow the determination of their enantiomeric composition even in complex mixtures. The absolute configuration of 4,6-nonadecanediol 7, occurring in the lipids of sunflower pollen, has been determined to be (4S,6R)
[反应:见正文]已开发出手性双齿甲硅烷基试剂用于脂肪族1,3-和1,4-二醇的GC分析。这些试剂与二醇反应生成环状硅氧烷,即使在复杂的混合物中也可以测定其对映体组成。通过与衍生化的合成对映异构体进行比较,已经确定了发生在向日葵花粉脂质中的4,6-十九碳二烯二醇7的绝对构型为(4S,6R)。
