Abstract

Substituted oxiranecarboxylic acids of the formula ##STR1## wherein R.sup.1 denotes a hydrogen atom (--H), a halogen atom, a hydroxyl roup, a lower alkyl group, a lower alkoxy group or a trifluoromethyl group, PA1 R.sup.2 has one of the meanings of R.sup.1, PA1 R.sup.3 denotes a hydrogen atom (--H) or a lower alkyl group and PA1 n denotes an integer from 1 to 5, and the salts of the acids are new compounds. They 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 are described.
