aliphatic thiols can be protected by reaction with t-BuMe2SiOCH2Cl in DMF in the presence of a base (2,6-lutidine or proton sponge); the resulting t-BuMe2SiOCH2SR or t-BuMe2SiOCH2SAr are deprotected by sequential treatment with Bu4NF and I2 to give symmetrical disulfides. Another mode of deprotection involves reaction with a sulfenyl chloride; this process gives an unsymmetrical disulfide and was examined
芳族和脂族硫醇可以通过与保护吨-BuMe 2的SiOCH 2氯在DMF中,在碱(2,6-二甲基吡啶或质子海绵)的存在; 所得吨-BuMe 2的SiOCH 2 SR或吨-BuMe 2的SiOCH 2 SAR通过用布顺序处理脱保护4 NF和我2,得到对称的二硫化物。脱保护的另一种方式涉及与亚磺酰氯反应。该过程产生不对称的二硫键,并用Me(CH 2)11 SCH 2 OSiMe 2 Bu-t和三个亚磺酰氯。
