Various 5-substitued 2-oxazolidinones were obtained by a ZnBr₂ catalyzed cyclization of N-Boc alkynylamines in toluene with DMAP as a base.The effects of catalyst type, alkali and temperature on the reaction were investigated.A series of target products were obtained with good yield under the optimized conditions.
- ZnBr₂,
- 4-Dimethylaminopyridine,
- N-Boc alkynylamines,
- 2-Oxazolidinones,
