A facile combinatorial strategy was developed for the construction of libraries of functionalized chiral ionic liquids (FCILs) including doubly chiral ionic liquids and bis-functional chiral ionic liquids. These FCIL libraries have the potential to be used as asymmetric catalysts or chiral ligands. As an example, novel asymmetric bifunctional catalysts were developed by simultaneously incorporating functional groups onto the cation and anion. The resultant bis-functionalized CILs showed significantly improved stereoselectivity over the mono-functionalized parent CILs. The Royal Society of Chemistry 2008.

Stereoisomers of distinct chiral amino acids were observed to occur in L-enantioenriched form in carbonaceous chondrite meteorites. Meteoritic amines and monocarboxylic acids were recently shown to occur in racemic ratio. In this study we investigated the electronic circular dichroism and anisotropy spectra of chiral alcohols, chiral amines, and chiral monocarboxylic acids. We recorded circular dichroism and anisotropy spectra from 280 to 170 nm in aqueous solution using a synchrotron-radiation ultraviolet circular dichroism spectrophotometer. The obtained anisotropy spectra are employed to discuss the likely role of ultraviolet circularly polarized light leading to enantioenriched amino acids, as well as racemic amines and monocarboxylic acids during their primordial interstellar synthesis. These data will moreover accompany the European Space Agency’s Rosetta mission, which successfully landed Philae on the nucleus of comet 67P/Churyumov?Gerasimenko to search for chiral organic molecules.
