Dutch resolution of racemates and the roles of solid solution formation and nucleation inhibition.

An overview is given of the principles of Pasteur resolutions via separation of diastereomeric salts.Thereafter, primary nucleation processes of (chiral) organic compounds in supersaturated solution are consideredfollowed by crystal growth in the presence of tailor-made additives. A representative example of a DutchResolution is presented, the concept of families of resolving agents is defined and examples are given.

The Dutch Resolution variant of the classical resolution of racemates by formation of diastereomeric salts: family behaviour in nucleation inhibition.

The resolution of racemates through their diastereomeric salts can be positively affected by the addition of small amounts of suitable nucleation inhibitors. This discovery is a logical extension of "Dutch Resolution", in which equimolar amounts of resolving agents that are members of the same family (i.e.
