  A Synthesis of d-erythro- and l-threo-Sphingosine and Sphinganine Diastereomers via the Biomimetic Precursor 3-Ketosphinganine

  摘要：

  The four stereoisomers of sphingosine and sphinganine can be produced in protected form by a short, convergent, biomimetic synthesis from serine. Yields are good (26-38% overall from commercially available serine derivatives), and the stereoselectivities are excellent (>92% de, >95% eel. Several sphingosine L-threo-sphingosine analogues with modified, functionalized tails were prepared to demonstrate the versatility of the method.
