In chemical drugs, nucleosides and their derivatives with therapeutic effect have a very important position, and their quantity is growing rapidly. Among them, 1-acetyloxy-2, 3, 5-triphenyloxy-1-beta-d-furanribose is the key intermediate of nucleosides and their derivatives. Nucleosides and drug chemistry are a new research field at home and abroad. Nucleosides or nucleotide analogues with antiviral activity are commonly called nucleoside antiviral drugs, which play an important role in the treatment of viral diseases.
