摘要

The present invention relates to hydantoins of formula I, in which R is the residue of an amino carboxylic acid or of an amino carboxylic acid derivative, which is obtained formally by removing an NH2 group from an amino carboxylic acid or an amino carboxylic acid derivative, to the preparation thereof and to the use thereof as intermediates, in particular for preparing pharmaceutically active ingredients.
