Stereoselectivities in the coupling reaction between 1-O-methyl-3,5-di-O-p-toluoyl-2-deoxyribofuranoside and suitably protected purine and pyrimidine derivatives have been examined in acetonitrile with varying equivalents of SnCl4. The best result in alpha-nucleoside formation was obtained when the coupling reaction was carried out in the presence of ten equivalents of SnCl4.
