Enantiopure aminotriol from D-isoascorbic acid synthesis of D-threo-C-18-sphingosine

Enantiopure suitably N,O-protected aminotriol has been prepared from D-isoascorbic acid. The utility of this homochiral building block in the synthesis of (2R,3R)-D-threo-C18-sphingosine is described via a Wittig reaction on a N,O-protected β-a
