1,3-Oxazolidin-2-ones from 1H-aziridines by a novel stratagem which mimics the direct insertion of CO2

Abstract

N-Ethoxycarbonylaziridines 2 undergo smooth thermal transformation into 1,3-oxazolidin-2-ones 3 on flash pyrolysis by a tandem reaction sequence equivalent to direct insertion of CO₂ into the parent 1H-aziridine.
