摘要

The synthesis of highly enantioenriched alpha-heterocyclic tertiary alcohols has been achieved via lithiation-borylation of a configurationally stable lithiated carbamate and heterocyclic pinacol boronic esters followed by oxidation. Protodeboronation of the alpha-heterocyclic tertiary boronic esters using TBAF center dot 3H(2)O or CsF gave highly enantioenriched 1-pyridyl-1-arylethanes in high er.
