English 10 October 2001 has decided to award the Nobel Prize in Chemistry for 2001 for the development of catalytic asymmetric synthesis, with one half jointly to William S. Knowles St Louis, Missouri, USA, and Ryoji Noyori Nagoya University, Chikusa, Nagoya, Japan, “for their work on chirally catalysed hydrogenation reactions” and the other half to…

Most chemicals that have an important role in biology exist as a pair of almost identical twins. These twins, called chiral enantiomers, contain exactly the same atoms, but they appear as mirror images that do not fit on top of each other, like placing your left hand on top of your right hand. Such a…

  The Nobel Prize in Chemistry 2001                   The word chiral derives from the Greek word ceir (cheir), meaning hand. Our hands are chiral – the right hand is a mirror image of the left – as are most of life’s molecules such as (R)-alanine and (S)-alanine,…

  The Nobel Prize in Chemistry 2001               The substances used as the starting point for these syntheses are in general not chiral. The trick is to make the product chiral. This is done using a chiral catalyst molecule. Suppose we compare this molecule with a left hand. A…
