Y. Ueno et al., SOLID-PHASE SYNTHESIS OF PEPTIDES CONTAINING O-PHOSPHORYL SERINE AND O-PHOSPHORYL THREONINE USING ALLYL GROUP FOR PHOSPHATE PROTECTION, Bioorganic & medicinal chemistry letters, 5(8), 1995, pp. 823-826
The preparation of Boc-Ser(PO(3)Allyl(2))-OH and Boc-Thr(PO(3)Allyl(2)
)-OH were described. Phosphorylated RE protein fragments were synthesi
zed using these O-phosphorylated amino acid building blocks in the Boc
mode of solid phase peptide synthesis.
