A new base-labile carboxyl protecting group, the 2-(4-acetyl-2-nitrophenyl)ethyl (Anpe) group is reported and compared with other base-labile protecting groups. The synthesis of the alcohol precursor, 1-[4-(2-hydroxyethyl)-3-nitrophenyl]-1-ethanone, the amino acid derivatives Boc-Asp(Anpe)-OH and Boc-Glu(Anpe)-OH and the conditions under which the carboxyl protecting group can be eliminated are also described.
报告了一种新的碱敏感羧基保护基团--2-(4-乙酰基-2-硝基苯基)乙基(Anpe)基团,并将其与其他碱敏感保护基团进行了比较。此外,还介绍了醇前体 1-[4-(2-羟乙基)-3-硝基苯基]-1-乙酮、氨基酸衍生物 Boc-Asp(Anpe)-OH 和 Boc-Glu(Anpe)-OH 的合成以及消除羧基保护基的条件。
