Solution-phase synthesis of an O-phosphoseryl-containing peptide using phenyl phosphorotriester protection: Solution-phase synthesis of an O-phosphoseryl-containing peptide using phenyl phosphorotriester protection. Perich, J. W.; Alewood, P. F.; Johns, R. B. (Dep. Org. Chem., Univ. Melbourne, Parkville 3052, Australia). Tetrahedron Lett., 27(12), 1373-6 (English) 1986. CODEN: TELEAY. ISSN: 0040-4039. DOCUMENT TYPE: Journal CA Section: 34 (Amino Acids, Peptides, and Proteins) Section cross-reference(s): 29 Title phosphopeptide H-Glu-Ser[P(O)(OH)2]-Leu-OH.CF3CO2H was prepd. from Boc-Ser[P(O)(OPh)2]-OH (Boc = Me3CO2C) by conventional soln. 2462-35-3 and 105751-09-5 which are cas registry numbers of substances are two of reagents here. methods using mixed anhydride coupling. Boc-Glu(OCH2Ph)-Ser[P(O)(OPh)2]-Leu-OCH2Ph was deblocked by hydrogenolysis in 40% CF3CO2H/AcOH to give H-Glu-Ser[P(O)(OPh)2]-Leu-OH.CF3CO2H (I). The Ph groups of I were cleaved by hydrogenolysis in 40% CF3CO2H/AcOH over 1 equiv PtO2/Ph group. .
