Abstract:

Carbohydrates are well-known substrates for stereoselective chiral pool synthesis, due to their known absolute configurations and developed methodology of selective manipulation of the –OH groups. Since both enantiomeric final products are sometimes necessary, D- and L- sugars should be available. Since D- and L-arabinose are easily available, we concentrated attention on them to obtain general building blocks for - hydroxycarboxylic acids synthesis. Alternatively, Dgalactose was used considering a fact, that it can be converted to its L-enantiomer. Consequently, both approaches are stereospecific.
