Related Products of 4426-11-3, 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. 4426-11-3, name is Cyclobutanecarbonitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
General procedure: tert-butyl 3 -( 1 -cyanocyclobutyl)-3 -hydroxypyrrolidine- 1 -carboxylate[619] To a solution of cyclobutanecarbonitrile (1.75 g, 21.5 mmol) in THF (15mL) was added 2.0M lithium diisopropylamide (11 mL, 22.5 mmol) dropwise and the solution was stirred at -78 C for 45 minutes. Then a solution of tert-butyl 3-oxopyrrolidine-l- carboxylate (4.0 g, 21.5 mmol) in THF (2 mL) was added to the solution and the mixture was stirred at -78 C for 2 hours. The reaction mixture was quenched with saturated NH4C1 solution and extracted with EtOAc (25 mL x 3). The organic phase was washed with brine (20 mL), dried over Na2S04, filtered, and concentrated. The residue was purified by column chromatography eluted with petroleum ether: EtOAc = 2: 1 to obtain the title compound (0.9 g, 38.2 % yield) as a white solid. XH NMR: (400 MHz, CDC13): ? 3.64-3.40 (m, 4H), 2.44 (t, J= 7.8 Hz, 2H), 2.33-2.23 (m, 2H), 2.13-1.88 (m, 4H), 1.47(s, 9H)
The synthetic route of Cyclobutanecarbonitrile has been constantly updated, and we look forward to future research findings.
