Rapid determination of enantiomeric excess

Synthesising compounds asymmetrically has obvious advantages – scientists don’t have to go through the laborious and wasteful process of separating then discarding the ‘wrong’ enantiomer. Huge libraries of compounds can be tested for their ability to catalyse a reaction of interest but determining the enantiomeric excess (ee) of the products is a bottleneck in the process.

So researchers have been developing high-throughput ee screening methods that can analyse samples as quickly as they are generated, ideally at a rate of a thousand or more per day.

Eric Anslyn and colleagues explore this topic in their Chem Soc Rev critical review, specifically focusing on optical methods. Download the review to find out about the advantages and drawbacks of a variety of techniques.
