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 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
