Crystallization of enantiomers : from the phase diagram to crystallization based enantioseparation

, 2007
Often it is not recognized that crystallization methods can be applied for enantioseparation purposes. Thus, the intention of this lecture is to present and to discuss several aspects relevant to derive the feasibility of crystallization based ...

Comparative study on the enantioseparation of glutethimide using dual cyclodextrin systems and cyclodextrin modified MEKC in capillary electrophoresis [PDF]

, 2002
peer reviewedIn order to critically evaluate the potential of dual cyclodextrin (CD) systems in CE, enantioseparation of the neutral chiral analyte glutethimide (GT) was performed using: a) charged CDs; b) combinations of charged and neutral CDs (dual CD

Cyclodextrin-Enabled Enantioselective Complexation Study of Cathinone Analogs

Molecules
The characteristic alkaloid component of the leaves of the catnip shrub (Catha edulis) is cathinone, and its synthetic analogs form a major group of recreational drugs. Cathinone derivatives are chiral compounds. In the literature, several chiral methods
