Abstract

The fusion reaction between 1-trimethylsilyl-naphth[2,3-d]imidazole (3) and its 2-methyl derivative (4) with 2, 3, 5-tri-O-benzoyl-1-bromo-D-ribofuranose (6) leads to anomeric mixtures of the corresponding 2', 3', 5'-tri-O-benzoyl-1α- and β-D-ribofuranosylnaphth[2,3-d]imidazoles (7, 11 and 13). Separation of the anomers was achieved by chromatographical means and debenzoylation yielded the corresponding nucleosides (8, 12 and 10, 14). Structural proofs are based on elementary analysis, UV-
