Phosphoric acid diesters of the formula:
and salts thereof are produced by reacting a-tocopherol with a halogenophosphorylating agent, reacting the resultant product with ascorbic acid having protecting hydroxy groups in the 5- and 6-positions, and removing the protected groups. The compounds can be employed as prophylactic and therapeutic agents for cataracts and climacteric hazards and also as an ingredient for cosmetics having skin-beautifying action.
