Abstract
An .omega.-amino group and/or .alpha.-amino group in an amino acid or a peptide can be protected with a 4-methoxy-2,3,6-trimethylbenzenesulfonyl group, and said group may easily be removed without affecting the amino acid or the peptide. Thus, the present invention is useful in the synthesis of peptide containing .omega.-amino group and/or .alpha.-amino group.
