4. Chiral catalysts can be designed to favor the formation of one enantiomer over another in reactions where a new chiral center is formed. The example shown below was recently reported in the chemical literature (J. Am. Chem. Soc. 2012, 134, 8054-8057) where a new type of chiral copper (Cu) catalyst was developed. When the Cu' catalyst was used, the (S)-enantiomer of the product predominated, and the (R)-enantiomer of the product was selectively formed when Cu" catalyst was used instead....
