A new chemical synthesis of D-tartronic acid semialdehyde phosphate and D-glyceric acid 2-phosphate

Abstract A short synthetic route for the preparation of D -tartronic acid semialdehyde phosphate and D -glyceric acid 2-phosphate from the readily available starting material, D -gluconolactone, is described. Enzymic tests of the two phosphate esters as inhibitor and substrate, of enolase, respectively, are reported.
