Ooh LA LA: The reductive amination of levulinic acid with a variety of aliphatic amines and aniline derivatives including stericallyhinderedamines is presented. The reaction is promoted by an iridium catalyst operating at low loading and 5 bar H2 under neat conditions. The catalyst was also efficient for the synthesis of N-aryl isoindolinone in high yields.

The synthesis of pyrrolidones via reductive amination of levulinic acid with aniline was examined over polypyrrolidone-stabilized metal nanoparticle catalysts. Among them, Ir metal was the most effective and applicable for the reductive amination of levulinic acid with nitroarenes/nitriles. Importantly, this catalyst was used for the one-potsynthesis of the anti-inflammatory drug indoprofen from 2-formylbenzoic
