## Reaction of a,&unsaturated sulphoxides with trtfluoroacetic anhydri& gives a,j+bis(trifhwroacetoxy)thioethers in near-quantitative yields. Subsequent basic methanolysis gives monomeric and dimeric a-hydroxyaldehydes or ahydroxyketones, &pending on the nature of the 8-R group. The former undergo W
&mm6fy : The four possible stereoisomers of a$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 a-hydroxyaldehydes as
