Imidazolines were prepared in one-pot operation from aldehydes and diamines through oxidation of aminal intermediates by NBS. This method could be applied to various aromatic and aliphatic aldehydes and N-nonsubstituted and N-monosubstituted 1,2-diamines. Furthermore, it was found that CH2Cl2 could be altered to TBME, a more environmentally friendly solvent, in the reaction using N-nonsubstituted 1,2-diamines. The reaction conditions were very mild and chemoselective.

2-Imidazolines were easily prepared in quite good yields from the reaction of aldehydes and ethylenediamine with molecular iodine in the presence of potassium carbonate. Moreover, 2-imidazolines obtained were smoothly oxidized to the corresponding imidazoles in good yields using (diacetoxyiodo)benzene at room temperature. Georg Thieme Verlag Stuttgart.
