Electric Literature of 1226781-82-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 1226781-82-3, name is tert-Butyl 2-(methylsulfonyl)-4,6-dihydropyrrolo[3,4-c]pyrazole-5(2H)-carboxylate belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
A solution of 2E (2.1 g, 7.3 mmol)Was dissolved in dichloromethane (25 mL)Cooled to 0 C, trifluoroacetic acid (5 mL) was added,Reaction for 2 hours.The reaction solution was concentrated, quenched by addition of aqueous ammonia (2 mL), and purified by silica gel column chromatography (dichloromethane / methanol (v / v) = 50: 1) to give intermediate 2 as a white solid.
The synthetic route of tert-Butyl 2-(methylsulfonyl)-4,6-dihydropyrrolo[3,4-c]pyrazole-5(2H)-carboxylate has been constantly updated, and we look forward to future research findings.
