Estimating chromatographic enantioselectivity (α) from gradient enantioselective chromatography data

Chirality, 2010
AbstractCalculation of chromatographic enantioselectivity (α) is critically important in enantioselective chromatographic method development studies. The fact that α can only be calculated from isocratic elution conditions, whereas gradient elution conditions are predominantly used in method development screening, presents some problems for the use of ...

Enantioselective

Angewandte Chemie (International ed. in English)
Even with only a catalytic amount of chiral bis(dihydrooxazole) 1 as external ligand, the rearrangement of benzyl ethers to alcohols [Eq. (1)] proceeds with high enantioselectivity (over 60 % ee). This reaction represents the first example of an enantioselective [1,2] Wittig rearrangement.
