There are five major chromatographic modes that can be applied to the analysis of solutes in solution normal phase, reversed phase, ion exchange, size exclusion, and affinity. In addition, a variety of submodes exist, such as hydrophobic interaction, chiral separations, ion suppression, and ion pairing.

The chiral recognition mechanisms that operate on the cellulosic CSPs have been studied by Wainer and co-workers (49,50). In one study, the chiral recognition of amides on the OB CSP was examined (49), The results indicated that the solute/CSP complexes formed between the OB CSP and the amide solutes were based on attractive hydrogen bonding, ti-tt, and dipole-dipole interactions. Chiral recognition within the solute/CSP complex was due to the differential inclusion (or fit) of the solute into a chiral cavity or ravine on the CSP However, studies with aromatic alcohols... 

Deviation from this conventional aggregation behaviour and appearance of more complex superstructures occur, like in biological systems, when specific non-covalent interactions, chirality, and secondary structure effects come into play [11,12]. Particularly interesting are block copolymers that combine advantageous features of synthetic polymers (solubility, process-...

The catalytic properties of these various crosslinked polymer-supported ephedrines have been tested in the asymmetric addition reaction of diethylzinc to benzaldehyde and the results are smnmarized in Table 10. The reactions were carried out either in toluene or hexane at 0°C or 20-23 °C. As it can be noticed in Table 10, the enantioselectivities were higher in toluene. Compared to linear polymers 153-155, lightiy crosslinked chiral polymers led to the best results in terms of yield and ee. The use of Amberlite XAD-4 and Polyhipe as support proved to be not efficient. It was assumed that probably for both supports the catalytic sites are more in the inner surfaces of the pores and that result in a high local concentration of aminoalcohol residue which lead to a significant site-site interaction. Chiral polymer 156a was also used in the asymmetric ethylation of 2-methoxybenzaldehyde and 4-chlorobenzaldehyde imder similar conditions and ees reached 90-93% when the reaction was performed at 0°C.
