Making carbon–carbon bonds is hard. Linking racemic mixtures of two alkyls while simultaneously controlling the stereochemistry of both ends of the product is nigh on impossible. Now Gregory Fu, ...

Chiral switches are chiral drugs that have already been claimed, approved and marketed as racemates or as mixtures of stereoisomers, but have since been redeveloped as single enantiomers. The ...

A racemic mixture of tartaric acid forms mirror-image domains with equal propensity when adsorbed on a copper surface. When one enantiomer is present in a slight excess, however, only ordered domains ...

Pharmaceutical process chemists use resolutions, or the separation of enantiomers from racemic mixtures, more than 60% of the time to generate chiral compounds. Among resolution methods, ...
