Abstract

Substituted oxocarboxylic acids of the formula I ##STR1## wherein R.sup.1 denotes a hydrogen atom, a halogen atom, a hydroxyl group, a lower alkyl group, a lower alkoxy group or a trifluoromethyl group, PA0 R.sup.2 denotes a hydrogen atom or a halogen atom and n denotes an integer from 3 to 8, and their salts display a hypoglycaemic action in warm-blooded animals. Processes for the preparation of the new compounds and of the intermediate products required for their preparation, as well as of the corresponding medicaments are described.
