The synthesis of primary and secondary pinacol boronic esters via
lithiation–borylation of carbamates and benzoates with pinacolborane is described. This new protocol enables the highly selective
synthesis of enantioenriched and geometrically defined boronic esters
that cannot otherwise be accessed by alternative methodologies.
