    摘要: The present invention provided optically active alcohols represented by the general formula:
        R¹-A- HCH₃

    wherein R¹ indicates an alkyl or alkyloxy group having a carbon number of 1-18, and A indicates a phenyl or a biphenyl group; or a phenyl or biphenyl group having a halogen atom or a cyano group. The alcohols are intermediates of optically active materials useful for components of liquid crystal materials for liquid crystal display elements having quick response.
