Synthesis of Non-Glutamate-Type Pyrrolo[2,3-d]Pyrimidines via Direct Aminocarbonylation of Aryl Halides Using Solid Co 2 (CO) 8 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-glutamate-type pyrrolo[2,3-d]pyrimidine analogues were prepared. Some compounds exhibited antibacterial activity against both Gram-positive and Gram-negative bacteria.
