Abstract
Substituted 4-oxoimidazolidines were prepared by the condensation of α-amino nitriles with carbonyl compounds, or by the self-condensation of α-amino nitriles. The mechanism of the reaction was studied. The mass spectrum of the condensation product obtained by the reaction of cyclohexanone with 1-amino-1-cyano-15N-cyclohexane (III) or by the self-condensation of III, and the ESR spectrum of corresponding nitroxide radical obtained by the oxidation of the respective condensation products served to elucidate the reaction mechanisms for these condensation reactions. The mechanism for the self-condensation of α-amino nitriles proposed previously was corrected from the spectral data of the reaction product. Possible mechanisms for these condensation reactions are proposed.
