Aziridines or 2-oxazolidones are readily prepared from unsaturated compounds by direct conversion into 4-chlorocarbamates followed by reaction with base or by pyrolysis, respectively. Yields are good and are comparable with those from the corresponding iodocarbamates. 8-Chlorocarbamates prepared from 1-olefins have chlcrine on C-2 and nitrogen on C-1; the oxazolidones obtained, therefore, are the 5-alkyl isomers. Proof of ...
