N-Benaylaminomethylsuccinic acid had been prepared by the addition of excess of benzylamine to itaconic acid in aqueous solution. N-Alkyl-palanines had been prepared by the addition of amines to acrylic acid. The reaction of primary aliphatic amines with methacrylic acid gave in some cases N-alkyl-8-aminoisobutyric acids and in other cases polymerization products. Aminomethylsuccinic acid, &alanine, and 8-aminoisobutyric acid ...
