    摘要: Organic nitrates, processes for their preparation and their use in the treatment of vascular diseases and in particular in the treatment of angina.The said nitrates correspond to the following formula I:R--CO--(A).sub.n --Y--B (I)in which:R represents, in particular, a sulphur-containing radical and a sulphur-containing amino acid residue; A represents, in particular, a CH.sub.2 group or a substituted amino acid; n is 0 or 1 or greater than 1; Y represents an oxygen atom or an NH group and B represents, in particular, a 1,4:3,6-dianhydro hexitol mononitrate radical, an itol nitrate radical or an inositol radical.The said organic nitrates are prepared by reacting:I. either a thio acid of the type R--COOH, in which R has the same meaning as above, with a derivative of formula II: (A).sub.n --Y--B, in which A, Y, B and n have the same meaning as above,II. or a derivative of formula III: R--CO--(A).sub.n, in which R, A and n have the same meaning as above, with a derivative of formula Y--B, in which Y and B have the same meaning as above, in an appropriate solvent and under non-epimerising conditions.
