Borate-Stabilized Transformation of C6 Aldose to C4 Aldose

Highly efficient transformations of biomass-derived sugars into various valuable chemicals are of topical interest. Tetrose with a four-carbon bone is the root of most of biomass-derived C4 products, but its extreme instability obstructs the blossoming of C4 products presently. Herein, we describe a...

Description
Summary:Highly efficient transformations of biomass-derived sugars into various valuable chemicals are of topical interest. Tetrose with a four-carbon bone is the root of most of biomass-derived C4 products, but its extreme instability obstructs the blossoming of C4 products presently. Herein, we describe a borate-stabilized catalytic strategy to accumulate erythrose from C6 aldose in a highly selective manner via retro-aldol and aldol processes in alcohol solvent. In our proposed mechanism, borate can stabilize erythrose and avoid its further retro-aldol splitting or isomerization, and induce the production of erythrose again via the aldol condensation of the above-generated glycolaldehyde.
