Extracurricular laboratory: Synthetic route of 2-(2-Oxopropyl)isoindoline-1,3-dione

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-(2-Oxopropyl)isoindoline-1,3-dione, other downstream synthetic routes, hurry up and to see.

3416-57-7, Adding a certain compound to certain chemical reactions, such as: 3416-57-7, name is 2-(2-Oxopropyl)isoindoline-1,3-dione, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 3416-57-7.

(1) Synthesis of N-[2-(N-methoxyimino)propyl]-phthalimide 1.33 g (6.55 mmol) of N-(2-oxopropyl)phthalimide was dissolved in 30 ml of ethanol and to the solution was added 1.64 g (19.7 mmol) of O-methylhydroxylamine hydrochloride. To this suspension was added 20 ml of 2N aqueous sodium hydroxide solution, followed by being stirred at room temperature for 12 hours. The reaction mixture was poured into 100 ml of water and extracted with chloroform (30 ml*3), and the combined organic layer was dried over magnesium sulfate. Chloroform was distilled off and the residual solids were washed with hexane to give 1.03 g (yield 68%) of the titled compound as colorless crystals. Melting point 114-131 C., 1 H-NMR spectrum (DMSO-d6, TMS as internal standard); delta=1.83(s, 3H), 3.73(s, 3H), 4.35(m, 2H), 7.82(s, 4H)ppm, IR spectrum (KBr); numax=2870w, 1680s, 1360s, 1315s, 1035s, 900w, 825m, 695m cm-1,
