Abstract
A proof of structure is presented for the title compound, previously uncharacterized. In the course of the investigation, the crystalline 2,3-O-isopropylidene acetals of calcium d-lvxonate, d-lyxono-1,4-lactone, d-lyxitol, β-d-erythrofuranose, calcium d-erythronate, and d-erythrono-1,4-lactone were prepared. The diacetate and dibenzoate of 2,3-O-isopropylidene-d-lyxose were also synthesized.
