Synthesis and Antiviral Activity of Novel Thieno[2,3-d]pyrimidine Hydrazones and Their C-Nucleosides

详细

A hydrazinylthienopyrimidine derivative reacted with a number of monosaccharides in the presence of a catalytic amount of acetic acid giving the corresponding sugar hydrazones, that undergo oxidative cyclization under the action of ferric chloride with formation of triazolo derivatives. Structures of the products have been elucidated from IR, ¹H, and ¹³C NMR data. Antiviral activity of the newly synthesized compounds is tested against influenza virus H5N1.
