A facile microwave-assisted method for the synthesis of tetramic acid derivatives I (R1 = Ph, Bn, 4-MeOC6H4, etc.; R2 = 3-F, 4-NO2, 3,4-(OMe)2, etc.; R3 = Ph, Bn, c-hexyl, 2,6-(Me)2C6H3) has been developed through an Ugi/Dieckmann cyclization strategy with DBU. This two-step one-pot procedure afforded the targeted tetramic acid analogs in good yields. With com. available Ugi starting materials, microwave irradiation, a simple operation, excellent yields, and a broad scope, this reaction has the potential to produce a large number of tetramic acid analogs, which cannot be easily accessed by the classic synthetic methods.
