Negishi cross-coupling reaction of racemic benzylic secondary alcohols with arylzinc compounds affords synthetically valuable enantioenriched 1,1-diarylalkanes in high yields and enantioselectivities.
A tertiary stereogenic center that bears two different aryl substituents is found in a variety of bioactive compounds, including medicines such as Zoloft™ and Detrol™. We have developed an efficient method for the synthesis of enantioenriched 1,1
