A large-scale, facile and stereoselective synthesis of 1-[5-O-(tert-butyldiphenylsilyl)-2,3-dideoxy-3-alpha-C-formyl-beta-D- erythro-pentofuranosyl] -adenine (7b) and -N-2-isobutyrylguanine (79) using an intermolecular radical C-C bond formation reaction is reported. The utility of these nucleosides (7b and 7c) as building blocks for antisense oligonucleosides is discussed.
