摘要

Azacyclic compounds of the formula in which X is the group of the formula -C(R3)R4-[C(R5)R6]p-[C(R7)R8]q- (Ia) or the group of the formula -N(R9)- (Ib), R1 is unsubstituted, monosubstituted or polysubstituted lower alkyl, lower alkenyl or lower alkynyl, where the substituents can be selected from the group consisting of hydroxyl and halogen, or is cycloalkyl, cycloalkenyl, phenyl-lower alkyl, phenyl-lower alkenyl or phenyl-lower alkynyl, R2 is carboxyl, 1H-tetrazol-5-yl, SO3H, PO2H2, PO3H2 or haloalkanesulphonylamino, either R3, R4, R5, R6, R7 and R8 independently of one another represent hydrogen, unsubstituted, mono- or polysubstituted lower alkyl, lower alkenyl or lower alkynyl, where the substituents can be selected from the group consisting of halogen, optionally etherified hydroxyl, optionally esterified or amidated carboxyl and optionally substituted amino, optionally esterified or amidated carboxyl, cycoalkyl, cycloalkenyl, an aliphatic hydrocarbon radical interrupted by O or an aromatic radical, or one of the three pairs of variables R3/R4, R5/R6 and R7/R8 represents a divalent aliphatic hydrocarbon radical and the variables of the two other pairs of variables independently of one another have the abovementioned meanings, R9 is hydrogen or unsubstituted, mono- or polysubstituted lower alkyl, lower alkenyl or lower alkynyl, where the substituents can be selected from the group consisting of optionally etherified hydroxyl and optionally esterified or amidated carboxyl, the indices p and q independently of one another represent 0 or 1 and the rings A and B, independently of one another, are optionally substituted, and if appropriate the tautomers thereof, in each case in free form or in the salt form, can be prepared in a manner known per se and can be used, for example, as pharmaceutical active substances.
