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. 90401-84-6, name is 6-Cyano-1-tetralone belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Application In Synthesis of 6-Cyano-1-tetralone
To a suspension of 5-oxo-5,6,7,8-tetrahydronaphthalene-2-carbonitrile (0.68 g, 4.0 mmol) in absolute ethanol (10 ml) were added methoxylamine hydrochloride (0.50 g, 5.9 mmol) and sodium acetate (0.49 g, 5.9 mmol). The suspension was refluxed for 3 h. The mixture was then concentrated under reduced pressure and the residue was dissolved in ethyl acetate (40 ml) and water (20 ml). The layers were separated and the organic layer was washed with brine (20 ml, dried over magnesium sulfate and concentrated over reduced pressure to afford 5-(methoxyimino)-5,6,7,8-tetrahydronaphthalene-2- carbonitrile (0.75 g, 92% yield, mixture 87: 13 of 2 stereoisomers) as a yellow solid. This compound was used in the next step without further purification. MS (ESI): 201 ([M+H]+)
The synthetic route of 90401-84-6 has been constantly updated, and we look forward to future research findings.
