    摘要: Phosphoric diesters of general formula:
    [wherein R₁ and R₂ are the same or different and each means a methyl group or a hydrogen atom, provided that at least one of R₁ and R₂ is a hydrogen atom, or a salt thereof] can be produced by reacting β, γ or δ-tocopherol with a halophosphorylating agent such as phosphorus oxychloride, reacting the resultant product with ascorbic acid whereof hydroxyl groups at 5- and 6-­positions are protected, and then removing protected groups from the hydroxy groups. The phosphoric diesters are novel compounds having antiinflammatory activity.
