Phosphorylated sugars. Part XX. Synthesis of 3-deoxy-D-manno-octulosonic acid 8-(dihydrogen phosphate)

Abstract
The title compound was obtained by base-catalysed condensation of 2-O-benzly-D-arabinose 5-phosphate with oxalacetate, followed by hydrogenolytic removal of the benzyl group. It was separated from the simultaneously formed D-gluco-isomer by ion-exchange chromatography.
