The synthesis of highly enantioenriched α-heterocyclic tertiary alcohols has been achieved via lithiation–borylation of a configurationally stable lithiated carbamate and heterocyclic pinacol boronicesters followed by oxidation. Protodeboronation of the α-heterocyclic tertiaryboronicestersusing TBAF·3H2O or CsF gave highly enantioenriched 1-pyridyl-1-arylethanes in high er.
