2'-OH, and 3'-phosphoryl functions, respectively. The units were converted to the OH or phosphodiester components by treatment with trifluoroacetic acid or with phosphinic acid-triethylamine. Both the components were appropriately coupled by means of mesitylenedisulphonyl chloride 3-nitro-1,2,4-triazole to give dimers in high yields. This method was successfully applied to the synthesis of GpUpApUpUpApApUpAp
