The chiral catalyst (R)-BINAP-Ru is used to hydrogenate alkenes to give alkanes (Section 6.7C). The
  products are produced with high enantiomeric excess. An example is the formation of (S)-naproxen, a pain reliever.


 
 

(a) What kind of isomers are the enantiomers of BINAP?
  (b) How can one enantiomer of naproxen be formed in such high yield?

(a) What kind of isomers are the enantiomers of BINAP?
The isomers are called atropisomers.
(b) How can one enantiomer of naproxen be formed in such high yield?
Because the catalyst is chiral, the hydrogenation reaction takes place in a chiral environment. When the chiral
groups on the catalyst are adjusted just right, high yields of a single enantiomer can be obtained.
