Novel chiral imidazolium and pyridinium ionic liquids based on tartaric acid and 2-oxazolidinone were designed. Sym. dicationic ionic liquids based on tartaric acid have been synthesized and characterized. These chiral ionic liquids were designed by employing very short and simple methods. Incorporation of alkyl halide over tartaric acid and 2-oxazolidinone is an important step. N-Me imidazole and pyridine were used for preparation of quaternary salts. These ionic liquids have been evaluated for the asym. sulfide oxidation Chiral ionic liquids based on tartaric acid showed superior chiral inducing property as compare to 2-oxazolidinone based chiral ionic liquids In the experiment, the researchers used many compounds, for example, (S)-4-Phenyloxazolidin-2-one (cas: 99395-88-7Electric Literature of C9H9NO2).
(S)-4-Phenyloxazolidin-2-one (cas: 99395-88-7) belongs to oxazolidine derivatives. Oxazolidine-based compounds have started to attract attention also in the medicinal and materials chemistry fields. Chiral oxazolidines are widely used as chiral auxiliaries, chiral ligands, protecting and/or directing groups in a variety of asymmetric transformations, thanks also to their easy cleavage or their further elaboration possibilities.Electric Literature of C9H9NO2
