5. Conclusion

The multiplicity of CSPs on the market is both a handicap (difficult choice) and a strength (possibility of solving all problems). There is no simple rule for choosing a CSP, especially as the choice is rarely unequivocal. However, we can propose a separation strategy based on the racemate structure (number and polarity of functional groups near its center of asymmetry, steric hindrance and conformational flexibility) [116] (figure 19...
