摘要

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 ...
