【Abstract】 The 1H and (13)C NMR spectra of the reaction products of α-bromoacrylamide derivatives and alanine were recorded in the reacting solution without being isolated.From the assignment of the spectral lines through different NMR techniques, the structure of the reaction product has been proved.It was found that the product is a mixture of equal amounts of two diastereoisomers of aziridine. The 1H and (13)C NMR spectra of stereoisomeric aziridines were discussed in the light of stereochemistry.The (13)C NMR spectra of diastereoisomeric aziridines discussed in this paper have never been reported in the literature before.更多还原
