A series of novel, photoregulated phosphoamino acid analogs based on an azobenzene core bearing an α,α-difluoromethylphosphonate as a hydrolytically stable phosphate isostere have been prepared with N-Fmoc protection for use in peptide synthesis. Classes of reagents analogous to both phosphotyrosine and phosphoserine/threonine were prepared by a common route employing a nitrosoarene/aniline condensation to form the azo linkage and the Cu(I)-promoted coupling of an iodoarene with (diethylphosphono)difluoromethyl cadmium bromide (Burton's method) to introduce the phosphonate moiety.
