Backwards is better: By combining forward and backward reaction steps of a reversible chemical process (see scheme) with the physical processes of crystallization, crystal crushing, and dissolution, asymmetric amplification up to 100 % ee can be achieved in the presence of racemic or achiralcatalysts starting from a conglomerate of the reactionproduct 1 with a low enantiomeric excess.
