Abstract

Various aromatic and aliphatic aldehydes were converted into the corresponding 2-aryl and 2-alkyl-2-oxazolines, respectively, in good to high yields by reaction with 2-aminoethanol and 1,3-diiodo-5,5-dimethylhydantoin. Moreover, chiral bis-2-oxazolines, which can be used as chiral ligands in asymmetric synthesis, could be also prepared in moderate yields by the reaction of dialdehydes with (R)-(-)-2-phenylglycinol under the same conditions.
