    • This invention relates to compounds of the formula: ##STR1## wherein R is an electron withdrawing group;R.sub.1 is H or COZ;X.sub.1 and X.sub.2 are independently H, lower alkyl, aryl, aryl lower-alkyl or polystyrene or R and X.sub.1 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; andZ 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.
    • 本发明涉及下式的化合物:其中R是吸电子基团; R1为H或COZ; X 1和X 2独立地为H,低级烷基,芳基,芳基低级烷基或聚苯乙烯,或者R和X 1与它们所连接的碳原子一起形成含有4至15个环碳原子的环,并且可含有至多2个 杂原子,其中杂原子是O,S或N; Z是氨基酸残基,肽残基或离去基团。 本发明的化合物适用于用于肽合成中的胺组合物的封闭或保护基团。 本发明还涉及在反应期间保护有机分子的氨基的方法,该方法修饰除了保护的氨基以外的分子的一部分。
