Abstract

Various fluorinated diphenylmethanols were enantioresolved by the methods of chiral camphorsultam-dichlorophthalic acid (CSDP acid) and/or 2-methoxy-2-(1-naphthyl)propionic acid (MalphaNP acid) yielding enantiopure alcohols. Their absolute configurations were unambiguously determined by X-ray crystallography of CSDP esters and/or by the (1)H NMR anisotropy method of MalphaNP esters for the first time.
