[摘要]：New [3+3] heterocyclization has been established for the synthesis of anti-tetrahydropyrimidine derivatives. The reaction was conducted by reacting readily available and inexpensive starting materials, such as 4-arylidene-2-phenyloxazol-5(4H)-ones, and aryl amidines, under solvent-free condition and microwave irradiation. During the reaction processes, the selective construction of anti-tetrahydropyrimidine skeleton and two amide functions were readily achieved via TEA-catalyzed ring-opening of oxazoles in a one-pot operation; in the meanwhile, lactone was converted into corresponding lactam in an intermolecular manner. |
