ABSTRACT:
There are prepared specific .alpha.-aminocarboxylic acids or their methyl, ethyl, or benzyl esters in which the .alpha.-amino group is substituted by a 3-cyanopropanoyl group. The compounds are useful for producing the corresponding derivatives of 4-aminobutyramide ("Gabamide") by catalytic hydrogenation of the cyano group.
