Basic hydrolysis (pyridine-water) of a 2,2,2-trifluoroethyl tyrosinyl 1-H-phosphonate diester affords predominantly a 2,2,2-trifluoroethyl 1-H-phosphonate mono-ester and tyrosine. The latter finding has been applied to the synthesis of a dipeptide consisting of a 1-H-phosphonylated serine and a non-1-H-phosphonylated tyrosine moiety.
