Abstract
meta‐Substituted diphenylmethanols were enantioresolved by the method of chiral phthalic acid yielding enantiopure alcohols. Their absolute configurations were unambiguously determined by X‐ray crystallography of chiral phthalate esters and/or by the 1H NMR anisotropy method using 2‐methoxy‐2‐(1‐naphthyl)propionic acid.
