Abstract

Procedure for the preparation of tripeptides derived from L-proline, of the general formula: **(See formula)** where R1 represents two hydrogen or one oxygen atom, R2 represents a hydrogen atom to an acyl group of 1 to 8 carbon atoms and R3 represents a hydrogen atom or an alcohol radical of 1 to 4 carbon atoms and where the 2nd amino acid residue corresponds to L-leucine, characterized by comprising the use of a reagent from the group consisting of diethylphonphoryl cyanide, 1-oeoxy-carbonyl-2-ethoxy-1,2-dihydroquinoline and dicyclohexylcarbodiimide as condensation agents between peptide units that make up the molecule, and a derivative of L-leucine from formulas **(See formula)** where Q represents an alkyloxy or aralkyloxy radical or a residue derived from glycine of the formula: **(See formula)** where W represents an alkyloxy radical of 1 to 4 carbon atoms or an amino radical or an alkylamino of 1 to 7 carbon atoms.
