Formal [3+2] Cycloaddition of Ketenes and Oxaziridines Catalyzed by Chiral Lewis Bases: Enantioselective Synthesis of Oxazolin‐4‐ones

Abstract

Der richtige Katalysator für eine hoch enantioselektive Synthese von Oxazolin-4-onen durch die formale [3+2]-Cycloaddition von Ketenen mit racemischen Oxaziridinen (siehe Schema) variiert: N-heterocyclische Carbene eignen sich für disubstituierte Ketene, Cinchona-Alkaloide für monosubstituierte Ketene: Ts=4-Toluolsulfonyl.
