Synthesis of non-glutamate-type pyrrolo[2,3-d]pyrimidines via direct aminocarbonylation of aryl halides using solid Co<sub>2</sub>(CO)<sub>8</sub> as a CO source and their antibacterial activity.
The synthesis of pyrrolo[2,3-d]pyrimidine derivatives by direct aminocarbonylation was demonstrated using solid Co2(CO)8 as a CO source in an autoclave at elevated temperature by reacting an aryl halide scaffold with a variety of amines. Using this method, 12 non-glutamatetype pyrrolo[2,3-d]pyrimidine analogues were prepared. Some compounds exhibited antibacterial activity against both Gram-positive and Gram-negative bacteria.
