and 1-chloro-2-deoxy-3,5-di-O-p-toluoyl-alpha-d-erythro-pentofuranose (6). The nucleoside was converted into the phosphoramidite and oligonucleotides were prepared by solid-phase synthesis. Oligonucleotide duplexes containing the 4-dC base pair show a similar stability as those containing the dG-dC motif. Thus the sterically demanding sulfur and the additional 8-oxo group are well accommodated in the
