Chemically,N-phosphoryl homo-serine was much more stable than the homologous compoundphosphorylated serine.The latter was very reactive to undergo N→O migration,formation of peptide and cyclophosphoroamidate but not the former when they were warmed in alcohol or chloroform at 40℃.For the N-phospho-homo-serine,only a small extent of ester exchange occurred on the phosphorus.A second type of penta-coordinate phosphorus intermediate was proposed.
