An efficient and convenient platform for the facile synthesis of phosphorylated ketoses is described. All eight phosphorylated ketopentoses were produced using this platform starting from two common and inexpensive aldoses (d-xylose and l-arabinose) in more than 84% isolated yield (gram scale). In this method, reversible conversions (isomerization or epimerization) were accurately controlled toward the formation of desired ketose phosphates by targeted phosphorylation reactions catalyzed by substrate-specific kinases. The byproducts were selectively removed by silver nitrate precipitation avoiding the tedious and time-consuming separation of sugar phosphate from adenosine phosphates (ATP and ADP). Moreover, the described strategy can be expanded for the synthesis of other sugar phosphates.
