3-Deoxy-D-arabino-hexonic Acid δ-Lactone 2,4,6-Triacetate is an intermediate in the synthesis of 3-Deoxy-D-arabino-hexonic Acid Calcium Salt (D232055), which has been shown to not play a major role in the initial hydrothermal decarboxylation of biomass. 3-Deoxy-D-arabino-hexonic Acid δ-Lactone 2,4,6-Triacetate is also an intermediate in the synthesis of Leptosphaerin.
