An optically active tri-substituted methane compound having, as substituents, an aromatic ring group and a phenyl group having hydroxyl group at ortho or para position can be obtained by allowing a phenol compound unsubstituted at the ortho- or/and para-position to react with an optically active secondary carbinol compound having an aromatic ring group at the alpha-position in the presence of tri-substituted phosphine and diazodicarboxylate or diazodicarboxamide. These and other optically active tri-substituted methane compounds are useful as active ingredients for medicines or as intermediate compounds for preparing medicines.
