Enantioselective synthesis of lyxo-(2R,3R,4R)-C18-phytosphingosine using double stereodifferentiation

lyxo-C18-Phytosphingosine can be synthesized by the cis-dihydroxylation of an (E)-allylic trichloroacetamide obtained by an Overman rearrangement. A double stereodifferentiation using AD-mix-β and an enantiomerically enriched (S)-allylic trichloroacetamide allowed the first synthesis of lyxo-(2R,3R,4R)-C18-phytosphingosine with high diastereoselectivity (de=94%) and excellent enantioselectivity (ee=93%). This sphingosine was fully characterized by the physical and spectral data of the corresponding tetraacetate. Copyright (C) 2000 Elsevier Science Ltd.
