    An alternative synthesis of calcium dobesilate, a simple venous insuficiency drug

  • Original language description

    Calcium dobesilate, calcium 2,5-dihydroxybenzensulfonate, a commonly used venous insufficiency and diabetic retinopathy drug, is usually synthetised according to original patent of Esteve-Subirana [6] by a "redox substitution" of 1,4-benzoquinone with calcium hydrogensulfite. This paper describes an alternative synthesis of this drug by sulfonation of hydroquinone with following neutralization of 2,5-dihydroxybenzenesulfonic acid with calcium carbonate. This preparative way is suitable also for use in chemical or pharmaceutical education, e.g. in practical exercises in Medicinal chemistry or in Organic chemistry.
