A series of 7-(het)aryl-7-deazapurine nucleobases (5-[(het)aryl]-2,4- disubstituted 7H-pyrrolo[2,3-d]pyrimidines) bearing NH2, OMe, SMe, or Me groups at position 6 and H, NH2, or Me at position 2 were prepared by the aqueous Suzuki-Miyaura cross-coupling reactions from SEM-protected 7-iodo-7-deazapurines with (het)arylboronic acids followed by deprotection. The 6-methoxy derivatives were further transformed into 7-deazahypoxanthines or 7-deazaguanines by O-demethylation reactions. Unlike their ribonucleoside counterparts, the 7-deazapurine nucleobases did not exert any significant cytostatic or antiviral effects.
