An enantioselective synthesis of the previously-disclosed ITK inhibitor GNE-6688 is described. Synthesis of the nitropyrazole fragment is highlighted by a Ru-catalyzed transfer hydrogenation using the Wills tethered ligand system. Synthesis of the pyrazole carboxylic acid fragment features an allylboration catalyzed by a chiral diol-SnCl4 complex, followed by a highly diastereoselective directed cyclopropanation.
