The 2,2,2-trichloroethoxycarbonyl (Troc) group has been successfully used as a protecting group for aminoacridines. Unlike aliphatic amines, deprotection of these aromatic amines yields significant amounts (12-29%) of stable 2,2-dichloroethoxycarbonyl (Dioc) by-products. Formation of bis-carbamates, through the introduction of butoxycarbonyl (Boc) moieties as temporary protecting groups, efficiently solves this problem.
2,2,2-三氯乙氧基羰基 (Troc) 基团已成功用作氨基吖啶的保护基团。与脂肪胺不同,这些芳香胺的脱保护会产生大量 (12-29%) 稳定的 2,2-二氯乙氧基羰基 (Dioc) 副产物。通过引入丁氧羰基(Boc)部分作为临时保护基团形成双氨基甲酸酯,有效解决了这个问题。
