Abstract
Isomerisation of cis and trans N-acyl-2-benzoyl-3-phenylaziridines to the corresponding N-(E) and N-[(Z)-1-oxo-1-aryl-3-phenylprop-2-en-2-yl]-4-benzamide, respectively, in the presence of diethyl thiourea is described. The structure of N-[(Z)-1-oxo-1-phenyl-3-phenylprop-2-en-2-yl]-4-nitrobenzamide is also confirmed by the single crystal X-ray diffraction study. A mechanism for this regiospecific rearrangement is proposed.
