Derivatives of p-aminophenyl-α-alanine and of p-aminophenyl-α-alanine and its dipeptides that contain the diethylenimidophosphoryl group

1. Some N-diethylenimidophosphoryl derivatives of p-aminophenyl-α-alanine and p-aminophenyl-β-alanine were synthesized. 2. Some dipeptides were obtained, in which N-(diethylenimidophosphoryl)-p-aminophenylalanine is either the N- or C-terminal amino acid.
