Environmental regulation and fossil resources depletion boost the search for new polymeric materials produced from biomass.

Here, we report the synthesis of a novel diester bearing a pendant lactam unit from methyl levulinate and aspartic acid. The palladiumcatalyzed reductive amination/cyclization sequence was carefully optimized to afford the diacid with high yield (>95 %).

In a second step, the compound was esterified to give the corresponding diester. The latter monomer was copolymerized with α-ω linear diols yielding polyesters with molecular weights up to 20.5 kg.mol-1 .
