About Willem Alberda Van Ekenstein
- In carbohydrate chemistry, the Lobry de Bruyn–van Ekenstein transformation also known as the Lobry de Bruyn–Alberda–van Ekenstein transformation is the base or acid catalyzed transformation of an aldose into the ketose isomer or vice versa, with a tautomeric enediol as reaction intermediate.
- Ketoses may be transformed into 3-ketoses, etcetera.
- The enediol is also an intermediate for the epimerization of an aldose or ketose.
- The reactions are usually base catalyzed, but can also take place under acid or neutral conditions.
- A typical rearrangement reaction is that between the aldose glyceraldehyde and the ketose dihydroxyacetone in a chemical equilibrium. The Lobry de Bruyn–van Ekenstein transformation is relevant for the industrial production of certain ketoses and was discovered in 1885 by Cornelis Adriaan Lobry van Troostenburg de Bruyn and Willem Alberda van Ekenstein.
