Pyridazine C-nucleosides have been synthesized by [4+2] cycloaddition of alkynyl C-nucleosides with substituted tetrazines. These pyridazines on extrusion of a nitrogen atom afforded novel pyrrole C-nucleosides with good yields. The results of electrochemical and chemical reduction are compared.

The invention relates to synthesis of a remdesivir key intermediate 2, 3, 5-tribenzyloxy-D-ribotide-1, 4-lactone. The invention discloses a synthesis method of 2, 3, 5-tribenzyloxy-D-ribotide-1, 4-lactone, and belongs to the field of organic synthesis. The method includes: taking D-ribose as an initial raw material, in methanol, using concentrated sulfuric acid as a catalyst, synthesizing a methoxy compound 2, then fully stirring the substances in a saturated sodium hydroxide solution, adding tetrahydrofuran and n-butylammonium hydrogen sulfate, and then adding benzyl bromide to synthesize a compound 3, dissolving the compound 3 in tetrahydrofuran and then performing catalysis with concentrated sulfuric acid, and performing reflux stirring overnight treatment to obtain a compound 4, dissolving the compound 4 into dichloromethane and water, adding sodium bicarbonate and TEMPO, slowly adding sodium hypochlorite at 0DEG C, raising the temperature to room temperature, and conducting stirring overnight treatment to obtain a compound 5. The method has the characteristics of easily available raw materials and low production cost, each process step is simple and easy to treat, the yield ofthe whole route reaches 43% or above, industrial production is easy to realize, and a basis is provided for industrialization of remdesivir and subsequent derivatives thereof.
