Diphenylmethyl (benzhydryl, Dpm) esters and ethers of amino acids and β-hydroxy-α-amino acids are prepared directly from N-unprotected L-α-amino acids using tris(diphenylmethyl) phosphate as alkylating agent. The novel H-Ser(Dpm)-ODpm and H-Thr(Dpm)-ODpm can be hydrolysed to the corresponding ethers H-Ser(Dpm)-OH and H-Thr(Dpm)-OH.
