Synthesis of Nα-(9-Fluorenylmethoxycarbonyl)-Allothreonine t-Butyl Ether via Threonine Oxazolines

New procedures for the preparation of allothreonine, suitably protected for solid phase peptide synthesis, were developed.Stereochemical inversion in the side chain of threonine via thionyl chloride-induced oxazoline cyclisation and subsequent hydrolysis, followed by protection of the allothreonine amino and hydroxyl functions provided Fmoc-D-alloThr(But)-OH from benzoyl-D-threonine phenacyl ester in only five steps.Alternatively, it was shown that temporary carboxyl protection for introduction of the t-butyl ether group can be circumvented by direct selective ester acidolysis from Fmoc-Thr(But)-OBut.
