Abstract: The invention relates to a process for the preparation of substantially pure enantiomers of (3-amino-3-carboxy-propyl)-alkyl phosphinic acid derivatives by asymmetric synthesis and to herbicidally and bioregulatory active pyrazine derivatives of the formula in which R denotes alkyl, R denotes hydrogen, alkyl or haloalkyl, R denotes hydrogen or alkyl, R denotes hydrogen or alkyl, R denotes hydrogen or alkyl, and R denotes alkyl or benzyl, which are used in this process.t
