摘要:背景:迄今为止,已经开发了许多用于羟基官能团的保护基.醇最常被保护为醚和酯,其中烷基和苄基醚是强保护基,而其他诸如thp,Tbs,Tps和mem / Mom醚则对酸不稳定.在所有其他羟基保护基中,甲硅烷基醚是最常用的保护基,因为它们易于安装且有效安装,并且对各种有用的试剂和反应条件稳定.在甲硅烷基醚中,三乙基甲硅烷基(tes),叔丁基二甲基甲硅烷基(tbdms),三异丙基甲硅烷基(tips)和叔丁基二苯基甲硅烷基(tbdps)部分是多步有机合成中常用的羟基保护基. 方法:一种温和,有效和选择性的方法,用于脱保护高产率开发的各种甲硅烷基醚,方法是在室温下在甲醇中使用20 Mol%的三氟甲磺酸锌(II)(zn(otf)2)作作为反应溶剂,而不影响两者报道了对酸和碱敏感的保护基. 结果:为了研究该方法的一般性,从具有不同保护基团的多种底物制备了几种甲硅烷基醚,并使用meoh中的zn(otf)2对其进行甲硅烷基化.
