The synthesis of the two 4-phosphono-2-aminobutanoyl-containing peptides, Leu-Arg-Arg-Val-Abu(P)-Leu-Gly-OH.CF3CO2H and Ile-Val-Pro-Asn-Abu(P)-Val-Glu-Glu-OH.CF3CO2H was accomplished by the use of Fmoc-Abu(PO3Me2)-OH in Fmoc/solid-phase peptide synthesis. The protected phosphoamino acid, Fmoc-Abu(PO3Me2)-OH, was prepared from Boc-Asp-OtBu in seven steps, the formation of the C-P linkage being
