Chiral matrixes

Likely, this idea will continue to be explored because new chiral matrices are created frequently. Examples of published possible stable chiral matrices are chiral microporous cross-linked polymers5 and nanoscale chiral helical columns created from various inorganic materials.6 However, the interface problem will still exist.

An important condition for chiral matrices is that they need to form labile interactions with the substrate in order to facilitate both the recovery of the enantioselec-tively coordinated ligand and the recycling of the chiral matrix. Usually copper(II) complexes have been used[48]. Due to the problems involved in the modeling of Jahn-Teller distorted copper(II) complexes (see Chapter 11 for a detailed discussion on...

Other applications include the separation of optical antipodes of drugs whose enantiomeric composition can be established conveniently and rapidly by gas chromatography. The effort of Bayer and his colleagues bring organic chemists one step closer to the synthesis of tailor-made chiral matrices. Like proteins they can undergo selective interaction with enantiomers from a wide variety of substances. 

The rather exciting and stimulating "phase transfer" synthetic procedure based on the use of polymer supported active functional moieties, such as onium groups, crown ethers, cryptands and poly-glymes, becomes even more naive when the active sites are bound to chiral matrices, whose prevalent chirality can be either intrinsi-...
