A novel class of chiral-amine-functionalized ionic liquids (CAFILs) has been synthesized efficiently from natural amino acids, and their structures have been determined by spectroscopic analysis and low temperature X-ray diffraction analysis. The CAFILs have been characterized by physical properties such as melting point, glass transition temperature, thermal degradation and specific rotation. NMR measurements indicate that the CAFILs may be promising alternatives in the field of chiral discrimination.

A library of new chiral iminoalkyl imidazolium salts has been synthesised from amino acids using a modular design approach. Deprotonation with silver oxide yields silver carbene transfer reagents, which can be used as ligand sources in asymmetric catalysis. Preliminary testing has shown that the ligands induce enantioselectivity in the palladium-catalysed allylic alkylation of 1,3-diphenylprop-3-enyl acetate with dimethyl malonate.

Aziridinylphosphinothionates were prepared from optically active ethyl hydrogen phenylphosphonothionates and 1-bromo-2-alkanamines derived from leucine or valine.The aziridine ring was opened by the action of some nucleophiles.Refluxing the aziridinylphosphinethionates in acetone with sodium iodide caused hydrolysis accompanied by the rearrangement of the sulfur atom to give β-mercaptoethylphosphonamidates.The reaction mechanism was discussed eith stereochemical considerations.The insecticidal activity of the products was also examined.
