The development of novel asymmetric reactions enhances both the variety of compounds available and the efficiency with which they can be produced. Chiral compound are hugely important in pharmaceuticals due to the chiral nature of biology. Herein, we describe the use of asymmetric organocatalysts in a Kemp elimination to produce chiral nitriles and fluoronitriles (Scheme I).

Scheme I Asymmetric Kemp elimination. We develop an enantioselective procedure for the synthesis of 3-ketosulfonates and the sulfonate directed reduction to 3-hydroxysulfonates. Further development o f this chemistry has lead to a variety o f sulfonate derivatives which could be used in chiral resolution as well as asymmetric organic synthesis (Scheme II).
