group is an excellent protecting group for steroid alcohols, giving volatile ethers, detectable at picogram levels in gas chromatography with an electron capture detector. By the use of five reagents, increasingly hindered hydroxyl groups can be protected, so that structural information about unidentified sterols can be obtained. Quantitative derivative formation for a wide range of hydroxyl groups
五氟苯基二甲基甲硅烷基是甾醇的极佳保护基团,可提供挥发性醚,可在气相色谱中用电子捕获检测器在皮克级检测到。通过使用五种试剂,可以保护日益受阻的羟基,从而可以获得有关未鉴定的甾醇的结构信息。通过选择正确的试剂组合,可以在不影响未保护的可烯醇化酮的情况下,为大量的羟基定量形成衍生物。
