Abstract: The tyrosine Ophosphorylation via AthertonTodd reaction, which was a classical reaction for phosphorylation amines, was first studied in this paper. Reaction of BocTyrOCH3, which was selected as model substrate, with three dialkyl Hphosphonate diester in the presence of CCl4 and triethylamine produced the corresponding tyrosine Ophosphorylation products in a high yield(over 80). The reaction was conducted in anhydrous THFsolution and monitored by 31P NMRand TLC. Then reaction of BocTyrOCH3 with a complicated Hphosphonate diester, O-3'-acetylthymidin-5'-yl Oisopropyl Hphosphonate diester, also gave a good result and this would be an alternative approach for the synthesis of nucleotide Otyrosine (or tyrosine containing peptide) conjugate. Further, the successful Ophosphoration of three tyrosine containing protected dipeptides, BocTyrValOCH3, BocAlaTyrOCH3, BocTyrTyrOCH3, with diisopropyl Hphosphonate diester demonstrated the effectiveness of the method.

Key words: AthertonTodd reaction, Dialkyl Hphosphonate diester, Tyrosine Ophosphorylation
