Abstract
A mild, efficient, highly regio- and enantioselective copper-catalyzed hydroboration of 1,1-diaryl substituted alkenes with bis(pinacolato)diboron provides a series of valuable β,β-diaryl substituted boronic esters with high enantiomeric purity. Moreover, this approach is also be suitable for hydroboration of α-alkyl styrenes for the synthesis of enantioenriched β,β-arylalkyl substituted boronic esters.
