A divergent coupling reaction was achieved between N-aryl epoxy amines and CO2. By using two different cocatalysts, tetrabutylammonium iodide (TBAI) or 4-dimethylaminopyridine (DMAP) together with an Al(III) Lewis acid, cyclic carbonates or oxazolidinones were selectively produced through two distinct reaction pathways, respectively. The proposed reaction mechanism was supported by the stereochemical determination of the products. A gram-scale production of Linezolid was successfully achieved.
Highly regioselective and efficient synthesis of aminoepoxides by ring closure of aminohalohydrins mediated by KF-Celite

The regioselective synthesis of several aminoepoxides has been achieved without observing any trace of azetidinols, which are usually reported as the exclusive reaction products when aminohalohydrins are treated with bases. The use of the mild supported base KF-Celite in refluxing acetonitrile is crucial for modulating the excellent regioselectivity observed. Georg Thieme Verlag Stuttgart . New York.
