G. Fantin et al., SYNTHESIS OF HOMOCHIRAL SYN AND ANTI-ALPHA-(HYDROXYETHYL)-GAMMA-BUTYROLACTONES VIA MICROBIAL REDUCTION, Tetrahedron : asymmetry, 5(9), 1994, pp. 1631-1634
Various yeast and mould strains were tested in the reduction of alpha-
acetyl-gamma-butyrolactone. -(3R,1'R)-alpha-(Hydroxyethyl)-gamma-butyr
olactone 2 and anti-(3R,1'S) isomer 3 were obtained enantiomerically p
ure. Good enantiomeric excesses are described for the corresponding en
antiomers.
