Alumina-Ammonium Acetate as an Efficient Reagent for the One-Pot Synthesis of cis-2,4,5-Triarylimidazolines from Aromatic Aldehydes
摘要:
A simple, efficient, and new method has been developed for the synthesis of 2,4,5-triarylimidazolines from aldehydes through a one-pot reaction of aldehydes in the presence of alumina-ammonium acetate under solvent-free conditions using microwave irradiation. This method is easy, rapid, one-pot and good to high-yielding reaction for the synthesis of 2,4,5-triarylimidazolines.
Novel data were obtained concerning the reaction of aromatic aldehydes with ammonia. A preparative method for the synthesis of new substituted 1,3,5-triaryl-2,4-diazapenta-1,4-dienes was developed. These products are the starting reactants for syntheses of cis- and trans-2,4,5-triaryl-2-imidazolines and 2,4,5-triarylimidazoles.
