Chemical synthesis chiral sensitivity

The ideal way to obtain pure drug enantiomers would be enantioselective synthesis. This, however, is rarely practical, usually complicated, and almost always expensive. There is little control over which chiral form of a chemical compound will be formed during a typical production process. This lack of control generally results in production of equal amounts of the various possible chiral forms of a compound. Often, therefore, separation of intermediates or final products from a racemic mixture is required. Increasing interest is being paid to development of methods of efficient, high throughput, and sensitive chiral separations, control of chemical synthesis, assessment...
