Abstract

6-amino carboxylic acid derivatives having antiasthmatic and antiallergic properties which can be used for the preparation of medicaments. The compounds have the formula: ##STR1## wherein R.sub.1 and R.sub.2 represent hydrogen, a straight-chain or branched alkyl radical with 1-6 carbon atoms, benzyl or phenylethyl, R.sub.3 represents hydrogen, a straight-chain or branched alkyl radical with 1-6 carbon atoms or benzyl, X represents hydrogen, halogen, C.sub.1 -C.sub.6 -alkyl or C.sub.1 -C.sub.6 -alkoxy, Y.sub.1 and Y.sub.2 represent hydrogen, halogen, C.sub.1 -C.sub.6 -alkyl or C.sub.1 -C.sub.6 -alkoxy, where m, n and o can assume the values from 0-4.
