It has been found for the first time at room temperature that the reaction of an unactivated 2-alkyl or 2-aryl aziridine with carbon dioxide to generate the corresponding oxazolidinone does not need any form of catalysis or solvent to proceed in high yield, especially when using high speed ball milling.

The conversion of an aziridine to a 1,2-diamine using lithium iodide and an iminium salt is discussed. We have found that when the aziridine is substituted by only alkyl groups, it is the less substituted carbonnitrogen bond that is broken; whereas, when the aziridine is substituted by a phenyl group at either the nitrogen or the carbon, it is the more substituted carbonnitrogen bond that is broken

The conversion of an aziridine to the corresponding oxazolidinone using only carbon dioxide and a catalytic amount of lithium iodide is discussed. In all cases, either no reaction occurred or a high yield of product was obtained. HMPA has been added to the reaction mixture, as needed, to drastically improve the regioselectivity.

A one-pot, inert atmosphere conversion of an aziridine to a β-lactam has been achieved, usingnickeltetracarbonyl, in which the less substituted C–N bond is carbonylated.
