1-金刚烷醇(英文名:1-Adamantanol),又称1-氢氧基金刚烷、1-三环[3.3.1.1(3,7)]癸醇,常温下为白色结晶粉末,熔点超过240℃。它溶于有机溶剂而不溶于水,并具有升华性。主要用途包括制造合成金刚烷衍生物和阿达巴林;与偏二氯乙烯反应可得1-金刚烷乙酸,后者再经过溴化、水解为3-羟基-1-金刚烷乙酸,进而与偏二氯乙烯反应得到1,3-金刚烷二乙酸。
此外,在98%硫酸介质中室温下,1-金刚烷醇可发生傅克烷基化反应直接合成1,3-二(4-乙酰氨基苯基)金刚烷,通过碱水解可进一步转化为1,3-二(4-苯胺)金刚烷。这种合成路线具有产率高、易提纯等优点,极大地便利了1,3-金刚烷二芳基衍生物的合成。
用途1-金刚烷醇主要用于合成金刚烷类化合物,并作为制造合成金刚烷衍生物和阿达巴林的关键中间体;此外,它还与偏二氯乙烯反应生成1-金刚烷乙酸。
Structurally diverse alcohols and phenols were trimethylsilylated in a clean and efficient reaction with hexamethyldisilazane (HMDS) based on the use of a catalytic amount of N-bromosuccinimide under both dichloromethane and solvent-free conditions at room temperature. Deprotection of trimethylsilyl ethers was also be achieved efficiently in the presence of a catalytic amount of NBS in methanol at ambient temperature.Key words: N-bromosuccinimide, solvent-free, alcohols, phenols, hexamethyldisilazane, trimethylsilyl ether, catalyst, detrimethylsilylation.
