Combinatorial synthesis of functionalized chiral and doubly chiral ionic liquids and their applications as asymmetric covalent/non-covalent bifunctional organocatalysts

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.

Irradiation of trans-1-benzoyl-2-trans-styrylcyclopropane (IIa) and trans-1-p-toluoyl-2-trans-styrylcyclopropane (IIb), leads to formation of cis disubstituted cyclopropanes (IIIa) and (IIIb) respectively.However, photolysis of trans-1-trans-cinnamoyl-2-phenylcyclopropane (IV) results in isomerzation of the alpha,beta-double bond to produce V.Photolysis of trans-1-trans-p-methoxycinnamoyl-2-p-methoxyphenylcyclopropane (VI), by contrast, produces only a cyclobutane dimer formulated as (VII).Irradiation of 7-phenyl-3-benzylidenespiro<2.5>octan-2-one (IXb), under identical conditions, leads to isomerisation around the C=C bond.The structural assignments are based, interalia, on 13C NMR and 1H NMR spectral data.

However, they have proven to be challenging because of the mutual inactivation of both catalysts. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 538-58-9

The effect of cyclohexene ring conformation on the diastereoselectivity observed for Simmons-Smith cyclopropanation of 2-cyclohexen-1-one ethylene ketals was examined by using (5S)-5-tert-butyl-2-cyclohexen-1-one 1,2-ethanediol, (2R,3R)-2,3-butanediol, and (2S,3S)-2,3-butanediol ketals.Reagent chelation by the pseudoequatorial dioxolane oxygen atom was shown to result in more effective methylene transfer.This regiochemical preference can either antagonize or reinforce diastereoselectivity due to steric hindrance of the dioxolane oxygen atoms from dissymmetric placement of methyl appendages on the dioxolane ring.
