We apply matched molecular pair (MMP) analysis to data from ChirBase, which contains literature reports of chromatographic enantioseparations. For the 19 chiral stationary phases we examined, we were able to identify 289 sets of pairs where there is

International audience; In this paper, we present several new theoretical measures based on information entropy that can be used to analyze the information content of a chiral molecule. Starting from a differentiation between "chiral" and "achiral" p

International audience; Predicting whether a chiral column will be effective is a daily task for many analysts. Moreover, finding the best chiral column for separating a particular racemic compound is mostly a matter of trial and error that may take

International audience; For the first time, chirality in (3 Z,9 Z)-1,2,5,8-dithiadiazecine-6,7(5 H,8 H)-dione series was recognized. Enantiomers of the 4,9-dimethyl-5,8-diphenyl analogue were isolated at room temperature, and their thermal stability

Separation & Purification Reviews. 37:229-301
The enantioseparation of 123 clinically used racemic drugs by supercritical fluid chromatography (SFC) on commercial chiral stationary phases (CSPs) available in 2006 is reviewed. The CSPs were briefly described in Part I of this work. The mobile pha

Information theory was used to analyse and compare organic syntheses leading to the targets, daucene, longifolene and estrone. This paper expands the work of Bertz, who analysed syntheses from the complexity of molecular structures. Herein, a more co
