A Wittig reaction employing Li(CD3)2CP(C6H5)3 was used to prepare d6-farnesol and d6-geranylgeraniol. Reductive amination of aniline-2,3,4,5,6-d5 was used to prepare the unnatural isoprenoid analogues d5-anilinogeraniol and d5-anilinofarnesol. All of these deuterated isoprenols were elaborated into their diphosphate and cysteine thioether derivatives suitable for use as stable-isotope labeled standards for quantitative mass spectrometric analysis.
使用 Li(CD3)2CP(C6H5)3 的 Wittig 反应合成了 d6-法尼醇和 d6-戊烯醇。利用 2,3,4,5,6-d5-苯胺的还原胺化反应合成了不自然的异戊烯类类似物 d5-苯胺戊烯醇和 d5-苯胺法尼醇。所有这些重氢化异戊醇均被转化为其二磷酸盐和半胱氨酸硫醚衍生物,这些衍生物适合用作定量质谱分析的稳定同位素标记标准。
