Synthesis of a Novel C-Nucleoside, 2-Amino-7-(2-deoxy-β- D-erythro-pentofuranosyl)-3H,5H-pyrrolo-[3,2-d]pyrimidin-4-one (2′-Deoxy-9-deazaguanosine)

Abstract

A synthesis of the C-nucleoside, 2-amino-7-(2-deoxy-β-D-erythro-pentofuranosyl)-3H,5H-pyrrolo[3,2-d]pyrimidin-4-one (9-deaza-2′-deoxyguanosine) was achieved starting from 2-amino-6-metnyl-3H-pyrimidin-4-one (5) and methyl 2-deoxy-3,5-di-O-(p-nitrobenzoyl)- D-erythro-pento-furanoside (11). The anomeric configuration of the C-nucleoside was established by ¹H NMR, NOEDS and ROESY. This C-nucleoside did not inhibit the growth of T-cell lymphoma cells.
