Several 4-substituted pyrrolo[2,3-d]pyrimidine 2′, 3′-dideoxyribofuranosides including 2′,3′-dideoxytubercidin (10) and 2′,3′-dideoxy-7-carbainosine (12) are prepared from 4-chloro-7-(2,3-dideoxy-β-D-glycero-pentofuranosyl)-7H-pyrrolo [2,3-d]pyrimidine (8). Compound 8 is obtained from the corresponding 4-chloro-7-(2-deoxy-β-D-erythro-pentofuranosyl)-7H-pyrrolo [2,3-d]pyrimidine (4a) via Barton-deoxygenation. Its protected precursor 3 is accessible in 81% yield by solid-liquid phase-transfer glycosylation.
