A composition of the formula: ##STR1## wherein X is lower alkyl, and Z is an amino acid a peptide residue or a good leaving group, the composition is adaptable as a blocking or protecting group for an amine composition useful in peptide synthesis and 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.
以下是该公式的组成部分:##STR1## 其中X是低碳基,Z是
氨基酸、肽残基或良好的离去基团,该组合物适用于阻断或保护肽合成中有用的
氨基组分,并且是一种在反应中保护有机分子的
氨基基团的方法,该反应修改的是除受保护
氨基组分以外的分子部分。
