- Facile Enzymatic Synthesis of Phosphorylated Ketopentoses
-
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.

Studies of rare ketoses have been hampered by a lack of efficient preparation methods. A convenient, efficient, and cost-effective platform for the facile synthesis of ketoses is described. This method enables the preparation of difficult-to-access ketopentoses and ketohexoses from common and inexpensive starting materials with high yield and purity and without the need for a tedious isomer separation step. A spoonful of sugar: A convenient, efficient, and cost-effective platform for the facile synthesis of ketoses is described. This method, which involves a one-pot mulitenzyme (OPME) reaction, enables the preparation of rare ketopentoses and ketohexoses from common and inexpensive starting materials with high yield and purity and without the need for a tedious isomer separation step.
