Abstract: PROBLEM TO BE SOLVED: To provide a chiral 1,3-dioxane compound and a diastereomer thereof, and to use the above compound as a chiral dopant for liquid crystalline system. SOLUTION: This chiral 1,3-dioxane compound is shown by the general formula I. This compound is suitable for producing cholesteric liquid-crystalline compositions, having relatively high torsional ability, and according thereto, exerting significant impact on the optical properties of liquid-crystalline host systems even in relatively small quantities.
