Optically active 2-aryl-1,3-oxazolines, such as aromatic carbocycles, heterocycle-binding 4-benzyl (or phenyl)-1,3oxazolines and their 5-benzyl (or phenyl)-l,3-oxazoline isomers were successfully prepared through a bromotriphenylphosphonium salt promoted aziridine ring formation and ring opening sequential process involving tandem one pot cyclization of chiral 2-amino-3-phenylpropanol or 2amino-2-phenylethanol with various aromatic acids in toluene at 90 °C in moderate to excellent yields. The mechanism of this tandem process was also substantiated experimentally.

(Chemical Equation Presented) N-Acyl-2-oxazolidinones are ring-opened by lithium iodide and decarboxylated in the presence of a mild proton source. Further reaction with an amine base provides 2-oxazolines. The transformation is general for oxazolidinones unsubstituted in the 5 position and occurs under mild conditions (25-50°C). These results complement the existing methods for this transformation by allowing lower temperatures and/or avoiding metal catalysts.
