Tetrahedron Letters | 1987

Product stereospecificity in the microbial reduction of imidazol-1-yl methyl aryl ketones

Randall Lis; Walton B. Caldwell; Gregory I. Rudd; William C. Lumma; Georg‐ A. Hoyer; Karl Petzoldt; Gerhard Cleve; Gerhard Sauer

Abstract Various microorganisms can be used to reduce ketoimidazole 3 to hydroxyimidazole 4. Only one enantiomer (i.e., (R)-4) is produced. In contrast, ketoimidazolium salt 2 is not reduced under identical conditions.
