摘要
2-Thioxo-3-alkyl-5-phenylmethylidene-4-imidazolidinones 5 were synthesized via tandem aza-Wittig reaction with three component of vinyliminophosphorane 3,alkyl isocyanates and Na2S/HOAc.The reaction condition and the spectral properties of cyclized compounds were researched.All the structures of cyclized products were confirmed by elemental analysis,IR,1H NMR and MS.
