Abstract

Procedure for the preparation of new heterocyclic carboxylic acids of the general formula I **(See formula)** in which X stands for oxygen or sulfur, Y means hydrogen or the methyl group, Z1 means halogen up to atomic number 17, the methyl or methoxy group, Z2 signifies hydrogen or the methyl group and R1 and R2 signify the methyl group or the ethyl group, as well as its salts with inorganic or organic bases, characterized in that a compound of the general formula II, **(See formula)** in which X, Y, Z1 and Z2 have the significance indicated under formula I, is reacted with a diketone of the general formula III, **(See formula)** in which R1 and R2 have the significance indicated under formula I, and a carboxylic acid obtained is transformed, if desired, with an inorganic or organic base into a salt.
