engaging the active site of IRAK4 and leveraging three-dimensional topology in a ligand-efficient manner, a micromolar hit identified from a screen of a Pfizer fragment library was optimized to afford IRAK4inhibitors with nanomolar potency in cellular assays. The medicinal chemistry effort featured the judicious placement of lipophilicity, informed by co-crystal structures with IRAK4 and optimization of ADME

The chiral pyrrolidine derivatives, 4-(hydroxymethyl)-3-azabicyclo[3.1.0]hexan-2-ones (10 and 11) and 5, 5-disubstituted 2-pyrrolidinones (20, 21 and 22), were synthesized starting from (S)-pyroglutamic acid and absolute configuration determination was made based on the 1H-NMR spectra of the bicyclic lactam intermediates.
