The reduction of 4-O-benzyl-2-methyl-3-oxo-butyrate esters by several fungal strains produces predominantly (2S,3R)-anti-hydroxyesters in high optical purity.The corresponding (2R,3R)-syn isomer was obtained, with other strains, only in mixture with the anti isomer.These esters are useful precursors for chiral 2-methyl-3-hydroxy-butyrolactone synthons.
