The synthesis of 7-(β-D-ribofuranosyl)-4-amino-5H-pyrrolo[3,2-d]pyrimidine (9-deazaadenosine) 9 is described. It involves base-catalyzed cyclization of N-carboethoxyenamine 4 to give β- and α-ribosylated 3-amino-2-cyanopyrroles 6 and 7, respectively, followed by a one-step conversion to the desired pyrrolo[3,2-d]pyrimidine system.
