Abstract
The invention provides a method for producing a peptide by (1) removing the N-terminal protective group of an amino acid or peptide compound of formula (I): wherein Y represents a residue of an N-protected amino acid or an N-protected peptide, and each of R, R, and Rindependently represents an aliphatic hydrocarbon group which may have a substituent or an aromatic hydrocarbon group which may have a substituent, wherein the total number of carbon atoms in the RRRSi group is 18 to 80, and the RRRSiCHCHgroup is bonded to the C-terminus of the amino acid or peptide residue in Y; and (2) causing condensation of an N-protected amino acid or an N-protected peptide and the N-terminus of the C-protected amino acid or C-protected peptide obtained in the step (1).
