Related Products of 181140-34-1, 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. 181140-34-1, name is (R)-(-)-N-(2,3-Epoxypropyl)phthalimide belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
To a solution of (R)-N-(2,3-epoxypropyl)-phthalimide (3.0 g, 14.8 mmol) and 2,4-dimethylphenol (1.6 g, 13.0 mmol) in toluene (30 mL) was added DBU (1.3 mmol) and the resulting mixture was heated at 120 C. for 18 h. The reaction mixture was cooled to 75 C., diluted with isopropanol (50 mL) and treated with hydrazine (4 mL). After stirring the mixture at 80 C. for 4 h, cooled to room temperature and solvents were evaporated in vacuo. The residue was dissolved in aq. NaOH (100 mL, 5 N) and extracted with chloroform (2×100 mL). The combined organic layer was washed with brine (100 mL) and dried over Na2SO4. The solvent was filtered and evaporated in vacuo to afford the desired product as an off-white solid. Yield: 1.7 g, 59% LCMS [M+H]+ 196.1 The product can be recrystallized from isopropyl alcohol.
The synthetic route of (R)-(-)-N-(2,3-Epoxypropyl)phthalimide has been constantly updated, and we look forward to future research findings.
