The stereoselective reduction of 2-butenolides by two reductases, p51 and p83, from cultured plant cells of Glycine max was investigated. The reduction of 2-methyl-2-butenolide by p51 reductase produced (R)-2-methylbutanolide, whereas the reduction by p83 reductase gave (S)-2-methylbutanolide. Both reductases reduced 3-methyl-2-butenolide to (R)-3-methylbutanolide. The reduction of 2,3-dimethyl-2-butenolide by p51 reductase gave (2R,3R)-2,3-dimethylbutanolide, whereas the reduction by p83 reductase produced (2S,3R)-2,3-dimethylbutanolide. The reduction of 4-alkyl-2-butenolides with these reductases was accompanied by resolution of chiral centers affording (R)-4-alkylbutanolides. (c) 2007 Elsevier Ltd. All rights reserved.
