Site-specific modification of glycosides to enhance or alter the physiological properties parent molecule has become a highly attractive strategy in drug development. However, creating glycoside building blocks with multiple diversifiable positions from readily available sugar precursors remains challenging task. Herein, we present regio- and stereoselective nickel-catalyzed carboboration glycals, which offers platform for generating diversity diverse C1 C2 potential.

Abstract In this study, we have developed a metal‐mediated synthetic method for incorporating the 1,1,2,2‐tetrafluoroethyl (CF 2 CF H) motif into unactivated, electron‐rich alkenyl iodides using cross‐coupling reactions. We discovered that stable Cu(CF H)(PPh Me) 3 complex, while unreactive with these substrates, serves as P‐ligated reservoir formation of solvent‐stabilized “ligandless” and reactive CuCF H species. This transformation occurs upon addition CuBr, which partially scavenges P‐ligand in form CuBr(PPh . The resulting situ generated solvent stabilized system significantly enhances reactivity particularly towards challenging substrates. advancement enables synthesis HCF ‐glycals, well nucleosides/nucleobases arenes.
