Some common heterocyclic compound, 181140-34-1, name is (R)-(-)-N-(2,3-Epoxypropyl)phthalimide, molecular formula is C11H9NO3, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Recommanded Product: (R)-(-)-N-(2,3-Epoxypropyl)phthalimide
A mixture of (R)-N-(2,3-epoxypropyl)-phthalimide (1.02 g, 5.0 mmol), phenol (5.0 mmol), p-xylene (2 mL) and DBU (0.05 mL) was stirred under N2 at 120 C. for 8 h. After cooling to 80 C. iPrOH (20 mL) and anhydrous hydrazine (1 mL) were added and the mixture was heated at 80 C. for 4 h. The reaction mixture was cooled to RT, 0.5N aq. NaOH (50 mL) was added, extracted with EtOAc (100 mL). Extract was washed with 0.5N aq. NaOH (50 mL), brine (50 mL), dried over Na2SO4 and evaporated. The residue was triturated with cold Et2O, the solid was collected by filtration, dried in vacuum.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 181140-34-1, its application will become more common.
