This invention relates to compounds of the formula:
wherein R is an electron withdrawing group;
R₁ is H or COZ;
X₁ and X₂ are independently H, lower alkyl, aryl, aryl lower-alkyl or polystyrene or
R and X₁ taken together with the carbon atoms to which they are attached form a ring containing from 4 to 15 ring carbon atoms and may contain up to 2 heteroatoms, wherein the heteroatoms are O, S, or N; and
Z is an amino acid residue, a peptide residue or a leaving group. The compounds of the present invention are adaptable as blocking or protecting groups for an amine composition useful in peptide synthesis. The present invention is also directed to a method of protecting an amino group of an organic molecule during a reaction which modifies a portion of the molecule other than the protected amino group.
本发明涉及式中的化合物:
其中 R 是取电子基团;
R₁ 是 H 或 COZ;
X₁ 和 X₂ 独立地为 H、低级烷基、芳基、芳基低级烷基或聚苯乙烯,或
R 和 X₁ 与它们所连接的碳原子一起形成一个环,该环含 4 至 15 个环状碳原子,最多可包含 2 个杂原子,其中杂原子为 O、S 或 N;以及
Z 是氨基酸残基、肽残基或离去基团。本发明的化合物可用作肽合成中胺类组合物的封端或保护基团。本发明还涉及一种在反应过程中保护有机分子氨基的方法,该反应改变了分子中除受保护氨基以外的部分。
