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. 85838-94-4, name is tert-Butyl 5,6-dihydropyridine-1(2H)-carboxylate, the common compound, a new synthetic route is introduced below. Recommanded Product: 85838-94-4
To a solution of 0.50 g (2.73 mmol) of tert-butyl 3,6-dihydro-2H-pyridine-i-carboxylate in 30 mL of DCM was added 0.92 g (4.09 mmol) of mCPBA. The resultant solution was stirred at 20C for 18 h. TLCindicated that the reaction was complete. The reaction was diluted with DCM, washed with aq. NaHCO3, aq. Na2S2O3 and brine, dried over Na2SO4, filtered and concentrated. The residue was purified by column chromatography (PE/EA, 5/i, R1= 0.2) to give 0.43 g of tert-butyl 7-oxa-4-azabicyclo[4.i.0]heptane-4- carboxylate as a colorless oil.MS (+ESI): 144.1 [M+H].?H NMR (400 MHz, CDC13) ppm: 4.09-3.58 (m, 2H), 3.57-3.02 (m, 4H), 2.18-1.84 (m, 2H), 1.47 (s,9H).
The synthetic route of 85838-94-4 has been constantly updated, and we look forward to future research findings.
