Using the concept that l-serine can be converted into a desymmetrized γ-diol derivative, five d-amino acids were synthesized from a common aziridine intermediate by a general, high-yielding three-step process. The key 2-t-butyldimethylsiloxymethyl N-t-butoxycarbonyl aziridine intermediate was synthesized in four steps and 65 % overall yield.
