Aldose; ketose; efficiency; interconversion; selectivity.

Of the methods analyzed, the most promising are the ones that use ionic liquids due to the fact that they are fast and largely selective, but developing the technology that uses this type of liquids for the interconversion of a particular aldose-ketose pair is a challenge for research in the coming years. A Window of Opportunities.
