L-2-Hydroxyaldehydes L-3 with a great variety of substituents in 3-position are obtained in good chemical and excellent optical yields by kinetic resolution in the transketolase-catalyzed reaction of racemic 2-hydroxyaldehydes with lithium hydroxypyruvate 4 where only the enantiomer (R)-3 reacts to 5-deoxy-D-xyluloses 5.

probes,* and chemical intermediate^.^ A recent review article reflects the importance of these compounds by enumerating hundreds of individual papers in the area of carbohydrate synthesis4 Traditional sources of rare or unnatural sugars have been chemical modification of natural sugars and total synthesis. The former was proven successful in many cases. However, total synthesis has evolved to a very
