摘要:An indole group in an amino acid or a peptide can be protected with a group shown by the formula: wherein R1 and R5 each is hydrogen, methyl or methoxy; R2 and R4 each is hydrogen or methyl; and R3 is methyl or methoxy, and said group may easily be removed without affecting the amino acid or the peptide to be derived from the protected amino acid or peptide. Thus, the present invention is useful in the synthesis of a peptide containing an indole group.

摘要:A guanidino group in an amino acid or a peptide can be protected with a specific group, i.e. pentamethylbenzenesulfonyl, 2,4,6-trimethoxybenzenesulfonyl, 4-methoxy-2,3,5,6-tetramethylbenzenesulfonyl, 4-methoxy-2,6-dimethylbenzenesulfonyl or 4-methoxy-2,3,6-trimethylbenzenesulfonyl, and said group may easily be removed without affecting the amino acid or the peptide to be derived from the protected amino acid or peptide. Thus, the present invention is useful in the synthesis of peptides containing the guanidino group.
