The reaction of diaryl ketones such as benzophenone with chiral epoxides in the presence of Yb metal at room temperature has been found to give chiral1,3-diols in high optical yields.

The enantiomers of chiral drugs may exhibit distinctly different pharmacokinetic and pharmacodynamic properties. Thus, the application of pure enantiomers is desirable in most cases. Therefore, it is necessary to know which enantiomer is the more advantageous one and to work out an economical large scale synthesis of this pure enantiomer. Biocatalytic transformations of prochiral compounds provide
