## Abstract A new diacid monomer **9** was synthesized in five steps. Starting from the reaction of Lโ€leucine with phthalic anhydride in acetic acid provided (2__S__)โ€4โ€methylโ€2โ€phthalimidylpentanoic acid (**3**) in good yield. The compound **3** was converted to (2__S__)โ€4โ€methylโ€2โ€phthalimidylpen
