As a common heterocyclic compound, it belongs to chiral-oxygen-ligands compound, name is 1,5-Diphenylpenta-1,4-dien-3-one, and cas is 538-58-9, its synthesis route is as follows.
General procedure: A Schlenk tube with a magnetic stir bar charged with alpha,beta-unsaturated carbonyl compounds (0.5 mmol, 1 equiv), tosyl hydrazide (0.6 mmol, 1.2 equiv), NaOH (1.5 equiv), (n-Bu)4NBr (1.5 equiv). The reaction vessel was placed in an 80 C oil bath, and then stirring at this temperature for 10 h. The reaction mixture was then allowed to cool to ambient temperature, and diluted with 20 mL of ethyl acetate, and washed with brine (15 mL), water (15 mL), and then the organic layer was dried over Na2SO4. After concentrated in vacuo, the crude product was purified by column chromatography. The identity and purity of the known product was confirmed by 1H NMR, 13C NMR, and GC-MS.
538-58-9, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,538-58-9 ,1,5-Diphenylpenta-1,4-dien-3-one, other downstream synthetic routes, hurry up and to see
