Abstract
2'-O-Tetrahydrofuranyl nucleosides have been synthesized from 2, 3-dihydrofuran via 3', 5'-bis-tert-butyldimethylsilylnucleosides. These nucleosides were used as intermediates for oligonucleotide syntheses by the phosphotriester method. Trimers C-C-A and C-C-U were synthesized by the stepwise addition of monomers. U-U-U-U-U-U, A-U-G-A-U-G and A-U-G-A-U-G-A-U-G were obtained by the block condensation of trimers in which the 5'-hydroxyl group had been selectively phosphorylated.
