An enantioselective radical-radical coupling using combined photoredox/N-heterocyclic carbene (NHC) catalysis was developed. The coupling of a ketyl radical and an sp3-carbon radical allows access to α-chiral ketones in moderate-to-good yields and enantioselectivities. Computational investigations reveal the N-heterocyclic carbene controls the double-facial selectivity of the ketyl radical and the

The design, synthesis, and biological characterization of an orally active prodrug (3) of gemcitabine are described. Additionally, the identification of a novel co-crystal solid form of the compound is presented. Valproate amide 3 is orally bioavailable and releases gemcitabine into the systemic circulation after passing through the intestinal mucosa. The compound has entered clinical trials and is
