cost-effective procedure has been devised for the preparation of urethane-protected 5-aminolaevulinic acid (5-ALA) dipeptide ester derivatives which avoids problems associated with the instability of 5-ALA under basic conditions. The procedure is also applicable to the direct synthesis of N-(α)-acetyl amino acid-ALA dipeptides in highenantiomericpurity as potential novel prodrugs for photodynamic therapy
