CHIRAL α-HYDROXY- AND α,β-DIHYDROXY-ALDEHYDES FROM D-ISOASCORBIC AND L-ASCORBIC ACIDS. USEFUL PRECURSORS FOR THE SYNTHESIS OF FATTY ACID METABOLITES.

The four possible stereoisomers of α,β-dihydroxyaldehydes, useful building blocks for the synthesis of fatty acids metabolites, are synthesized via epoxy-tetrols derived from D-isoascorbic and L-ascorbic acids.The general method we develop allows the synthesis of chiral α-hydroxyaldehydes as well.
