Polymer-assisted solution-phase (PASP) library synthesis of alpha-ketoamides
A parallel solution-phase library synthesis of alpha-ketoamides is described. The two-step library synthesis is accomplished using polymer-assisted solution-phase (PASP) synthesis techniques. This high-yielding, multi-step sequence utilizes sequestering resins for the removal of reactants, reactant by-products, and tagged reagents. The first step of the library synthesis utilizes PASP resins to mediate the amide coupling of an alpha-hydroxy acid with an amine. The second step uses PASP resins for the periodinane oxidation of the oi-hydroxy acid to an alpha-ketoamide leaving highly pure products after simple filtration and evaporation.
