A method for preparing peptides is disclosed, the method comprising a step of forming a peptide bond wherein the carboxyl group of a first amino acid or first peptide is activated and an amino group of the first activated amino acid or first peptide is protected by a protecting group having a water-solubility enhancing group and the activated carboxyl group of the first amino acid or first peptide is reacted with an amino group of a second amino acid or second peptide wherein said carboxyl group of the first amino acid or first peptide is activated in the absence of the second amino acid or second peptide. Peptides comprising a protecting group having a water-solubility enhancing group being bound to the amino group and an activated or free carboxyl group are also disclosed.

Method for preparing peptides

The invention relates to a method for peptide synthesis, wherein said method comprises the steps of reacting a first amino acid or a first peptide with an &#x3b1;-amine protected second amino acid in a solvent selected from the group consisting of water, alcohol, and a mixture of water and alcohol, and removing the &#x3b1;-amine protecting group with a deprotecting solution. The invention further relates to protective agents, their use and an apparatus for carrying out a method for solid phase synthesis of peptides.
