Problems solved by technology

The article "Revised Structure of the Adrenochrome Sulfonate, Ac-17and Ac-44" published by Mitsutaka Kawazu et al. provides a method for synthesizing sodium carbosulfonate. The method uses adrenaline as a raw material and undergoes cyclization under the action of silver oxide to generate Adrenaline red, adrenaline red and semicarbazide are substituted to form carbacide, and carbacide reacts with a weakly alkaline reducing agent to generate carbacin sodium. This synthetic method has many steps, and more expensive reagents are used in the reaction. The operation is also complicate
