Fmoc/solid-phase synthesis of Tyr(P)-containing peptides through t-butyl phosphate protection.[Pubmed:1717394]
Int J Pept Protein Res. 1991 Jun;37(6):572-5.
The synthesis of Tyr(P)-containing peptides by the use of Fmoc-Tyr(PO3Me2)-OH in Fmoc/solid phase synthesis is complicated since, firstly, piperidine causes cleavage of the methyl group from the -Tyr(PO3Me2)-residue during peptide synthesis and, secondly, harsh conditions are needed for its final cleavage. A very simple method for the synthesis of Tyr(P)-containing peptides using t-butyl phosphate protection is described. The protected phosphotyrosine derivative, Fmoc-Tyr(PO3tBu2)-OH was prepared in high yield from Fmoc-Tyr-OH by a one-step procedure which employed di-t-butyl N,N-diethyl-phosphoramidite as the phosphorylation reagent. The use of this derivative in Fmoc/solid phase peptide synthesis is demonstrated by the preparation of the Tyr(P)-containing peptides, Ala-Glu-Tyr(P)-Ser-Ala and Ser-Ser-Ser-Tyr(P)-Tyr(P).
Chemical synthesis of O-thiophosphotyrosyl peptides.[Pubmed:8200732]
Int J Pept Protein Res. 1994 Feb;43(2):146-53.
The synthon for O-thiophosphotyrosine, Fmoc-Tyr[PS(OBzl)2]-OH (1c), was prepared in 63% yield from Fmoc-Tyr-OH by first transient protection as the tBuMe2Si-ester and phosphinylation with (BzlO)2PNiPr2/tetrazole followed by oxidation of P(III) to P(V) with S8 in CS2. Building block 1c was incorporated in the Fmoc solid-phase synthesis of two O-thiophosphotyrosine-containing peptides H-Thr-Glu-Pro-Gln-Tyr(PS)-Gln-Pro-Gly-Glu-OH (2) and H-Thr-Arg-Asp-Ile-Tyr(PS)-Glu-Thr-Asp-Phe-Phe-Arg-Lys-OH (3), corresponding to sequences of the p60src (523-531) protein and an insulin receptor (IR) (1142-1153) analogue, respectively. An alternative approach of synthesis, the global phosphorylation of a resin-bound peptide, also proved useful. Thus, the free tyrosyl side-chain containing-peptide IR (1142-1153) on support was phosphinylated with the above phosphoramidite reagent followed by oxidation with either S8/CS2 or tetraethylthiuram disulfide/CH3CN solutions. Deprotection and peptide-resin cleavage was performed with a TFA/thiophenol (H2O) mixture. Crude peptides 2 and 3 were stable to the acidolytic deprotection. Preparative RP(C18)HPLC was initially performed using 0.1% TFA(aq)/EtOH solvents. However, analyses of fractions resulting from the purification step indicated significant decomposition of thiophosphopeptide in solution. Stability measurements both as a function of time and pH, further confirmed this initial finding. Purifications performed at intermediate pH using a triethylammonium acetate (pH 7.5)/CH3CN solvent system overcame this problem.
Efficient solid phase synthesis of mixed Thr(P)-, Ser(P)- and Tyr(P)-containing phosphopeptides by "global" "phosphite-triester" phosphorylation.[Pubmed:1280250]
Int J Pept Protein Res. 1992 Aug;40(2):134-40.
The synthesis of the mixed Thr(P)/Tyr(P)-containing peptide, Ala-Thr(P)-Tyr(P)-Ser-Ala, was accomplished by "phosphite-triester" phosphorylation of the resin-bound Thr/Tyr-containing peptide using di-t-butyl N,N-diethylphosphoramidite as the phosphitylation reagent. The pentapeptide-resin was assembled by Fmoc/solid-phase peptide synthesis with the use of PyBOP as coupling reagent and the hydroxy-amino acids incorporated as side-chain free Fmoc-Tyr-OH and Fmoc-Thr-OH. "Global" bis-phosphorylation of the peptide-resin was accomplished by treatment with di-t-butyl N,N-diethylphosphoramidite/1H-tetrazole followed by m-chloroperoxybenzoic acid oxidation of the intermediate di-t-butylphosphite triester. Simultaneous peptide-resin cleavage and peptide deprotection was effected by treatment of the peptide-resin with 5% anisole/TFA and gave the Thr(P)/Tyr(P)-containing phosphopeptide in high yield and purity. In addition, the tyrosyl residue was found to be phosphitylated in preference to the threonyl residue since the phosphitylation of the pentapeptide-resin using only 1.1 equiv. of di-t-butyl N,N-diethylphosphoramidite gave Ala-Thr-Tyr(P)-Ser-Ala as the major product and both Ala-Thr(P)-Tyr(P)-Ser-Ala and Ala-Thr-Tyr-Ser-Ala as minor products.
