(Chemical Equation Presented) Trisubstituted allylic pentafluorobenzoates react with diorganozinc reagents in the presence of CuCN·2 LiCl to provide alkenes bearing a chiral quaternary center in α position (> 95 % ee). These alkenes are readily converted into chiral tertiary alcohols or into chiral amino alcohols by a straightforward sequence of ozonolysis followed by Curtius rearrangement (see scheme).
