Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 17983-30-1, name is 3-Oxocyclohexanecarbonitrile, A new synthetic method of this compound is introduced below., Safety of 3-Oxocyclohexanecarbonitrile
Under a nitrogen atmosphere, lithium aluminum hydride (92 mg, 2.44 mmol) was added to a solution of 1-cyanocyclohexan-3-one (100 mg, 0.812 mmol) in tetrahydrofuran (2 ml) at room temperature, and the resulting mixture was refluxed. After 5 hours, water, an aqueous sodium hydroxide solution and water were added in that order to the reaction solution, and the resulting mixture was filtered under reduced pressure. Thereafter, 1M-hydrochloric acid-diethyl ether (974 mul, 0.974 mmol) was added to the filtrate. The resulting mixture was concentrated under reduced pressure, and to an aqueous solution (4 ml) of the resulting residue were added potassium carbonate (202 mg, 1.46 mmol), ethoxycarbonylphthalimide (196 mg, 0.893 mmol) and acetonitrile (1 ml) at room temperature. After 21 hours, the reaction solution was poured into water and extracted with ethyl acetate, and the organic layer was dried over anhydrous magnesium sulfate. The organic layer dried was concentrated under reduced pressure and the resulting residue was purified by a silica gel column chromatography (eluent: hexane/ethyl acetate) and purified again by a silica gel column chromatography (eluent: chloroform/ethyl acetate) to obtain cis-2-[(3-hydroxycyclohexyl)methyl]-1Hisoindole-1,3(2H)-dione (83.5 mg, 40%, cis : trans = 12 : 1).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
