New polyarylates having benzopinacolone units were synthesized from 2,2-bis(4-hydroxyphenyl)-1,2-diphenylethanone and aromatic dicarboxylic acid chlorides. The polymers having an inherent viscosity of 0.71-0.94 dL/g were obtained by the two-phase method using toluene as an organic solvent. The polym

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