In this work, a new method for highly efficient and selective oxidative deprotection of a variety of structurally diverse trimethylsilyl (TMS) and tert-butyldimethylsilyl (TBS) ethers using molecular oxygen in the presence of N-hydroxyphthalimide (NHPI) and various types of Co(II) complexes is reported. As a result of the relatively neutral reaction medium, acid-sensitive functional groups such as
在这项工作中,一种在N-羟基邻苯二甲酰亚胺(NHPI)和各种类型的Co的存在下,使用分子氧对多种结构多样的三甲基甲硅烷基(TMS)和叔丁基二甲基甲硅烷基(TBS)醚进行高效且选择性氧化脱保护的新方法(二)络合物的报道。作为相对中性的反应介质的结果,酸敏感性官能团例如酚类TBS醚在提出的反应条件下完整保存。
