Related Products of 141452-01-9, These common heterocyclic compound, 141452-01-9, name is Methyl indoline-5-carboxylate, its 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.
In the dried Schrank tube, raw porphyrin (0.15 mmol, 32.8 mg), p-toluenesulfonamide (0.3 mmol, 51.1 mg),Iodobenzene acetate (0.15 mmol, 48.3 mg), pentamethylcyclopentadienylphosphonium dichloride (5 mmol%, 4.6 mg), silver triflate (20 mmol%, 7.7 mg),Silver acetate (20 mmol%, 5.1 mg), acetic acid (0.45 mmol, 27 mg)1.5 mL of 1,2-dichloroethane, and the above-mentioned Schalke tube was placed in a 100 o C oil bath.Stir for about 16 h. Stop the reaction and use 2 mLSaturated ammonium chloride is easy to quench the reaction solution.After further extraction with ethyl acetate (4 mL × 5), the organic phases were combined.The solvent was removed on a rotary evaporator. At last,Separated by silica gel column chromatography (eluent: ethyl acetate: petroleum ether = 1: 5),Methyl 1-acetyl-7-((4-methylphenyl)sulfonylamino)indoline-5-carboxylate3i (26.1 mg, isolated yield: 45%),This compound was a pale yellow solid.
The synthetic route of 141452-01-9 has been constantly updated, and we look forward to future research findings.
