The reaction of β-lactam carbenes with 3,6-di(2-pyrimidinyl)tetrazine: regulating products by reaction conditions

The reaction of β-lactam carbenes with 3,6-di(2-pyrimidinyl)tetrazine was studied, which produced good yields of novel 5-(3-[1,2,3]triazolo[1,5-a]pyrimidinyl)pyrrol-2-ones or pyrrolo[3′,2′:3,4]pyrrolo[1,2-a]pyrimidin-2-ones under heating at 100 °C or 140 °C, respectively. This work provided a highly...

Description
Summary:The reaction of β-lactam carbenes with 3,6-di(2-pyrimidinyl)tetrazine was studied, which produced good yields of novel 5-(3-[1,2,3]triazolo[1,5-a]pyrimidinyl)pyrrol-2-ones or pyrrolo[3′,2′:3,4]pyrrolo[1,2-a]pyrimidin-2-ones under heating at 100 °C or 140 °C, respectively. This work provided a highly efficient strategy for the construction of both [1,2,3]triazolo[1,5-a]pyrimidine and pyrrolo[3′,2′:3,4]pyrrolo[1,2-a]pyrimidine ring systems from the same reactants, and extended the application of β-lactam carbenes in the syntheses of complex heterocycles.
