The present invention relates to new compounds of general formula I. in the A and B can be the same or different and each represents a hydrogen atom, an alkyl, alkenyl, alkynyl, benzyl or a cycloalkyl group, R₁ represents a hydrogen atom, an alkyl, alkenyl or a cycloalkyl group, R₂ represents a hydrogen atom, an alkyl, alkenyl, cycloalkyl, alkylcarbonyl, alkoxycarbonyl, aminocarbonyl or hydrazinocarbonyl group or R₁ and R₂ together with the carbon atom to which they are attached form a cycloalkyl ring, n can assume the values 0 or 1, X represents a bond or an alkylene group, R₃ represents an aromatic heterocyclic, substituted or unsubstituted five or six ring, the five or six rings with a phenyl ring or another aromatic five or six ring can be fused to a bicyclic group, which is alkyl, alkoxy, alkoxycarbonyl, carboxyl -, Alkylmercapto, hydroxy, nitro, amino, halogen or cyano groups may be substituted, or R₃ represents a substituted or unsubstituted phenyl or naphthyl radical.n n n The invention further relates to processes for the preparation of compounds of the general formula I and medicaments containing these compounds for the treatment of cardiovascular diseases. The starting materials used to prepare the compounds are new and also the subject of the invention. |
