The synthesis of oligonucleotidescontaining N7-(2-deoxy-β-D-erythro-pentofuranosyl)guanine (N7Gd; 1) is described. Compound 1 was prepared by nucleobase-anion glycosylation of 2-amino-6-methoxypurine (5) with 2-deoxy-3,5-di-O-(4-toluoyl)-α-D-erythro-pentofuranosyl chloride (6) followed by detoluoylation and displacement of the MeO group (8101). Upon base protection with the (dimethylamino)methylidene
