Reference of 423116-18-1, 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. 423116-18-1, name is 2-(4-Oxocyclohexylmethyl)isoindole-1,3-dione belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
Sodium cyanoborohydride (48.5 g, 772 mmol) was added portionwise to a solution of 2-((4-oxocyclohexyl)methyl)isoindoline-1,3-dione (100 g, 389 mmol, Intermediate 28) in AcOH (1.0 L), and the resulting mixture was stirred at rt for 16 h. After this time, the mixture was concentrated, and the concentrate was dissolved in EtOAc. The resulting solution washed twice with a saturated aqueous NaHCO3 solution, dried with anhydrous Na2SO4, filtered, and concentrated to afford the title compound as a colorless solid, which was used in the next step without further purification.
The synthetic route of 2-(4-Oxocyclohexylmethyl)isoindole-1,3-dione has been constantly updated, and we look forward to future research findings.
