Vicinal stereocenters are found in many natural and unnatural compounds. Although metal‐catalyzed cross‐coupling reactions of unactivated alkyl electrophiles are emerging as a powerful tool in organic synthesis, there have been virtually no reports of processes that generate, much less control, vicinal stereocenters. In this investigation, we establish that a chiral nickel catalyst can mediate doubly...
The enantioselective desymmetrization of cyclic meso‐anhydrides with benzyl trifluoroborates under nickel‐photoredox catalysis is described. The reaction tolerates a variety of sterically and electronically different trifluoroborates, as well as structurally unique cyclic anhydrides. The trans isomer of the keto‐acid products is also observed at varying levels dependent on the trifluoroborate identity...
