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.,538-58-9
General procedure: A flask equipped a magnetic stirring bar was charged with alpha,beta-unsaturatedketone 1 (1.0 mmol), tosylhydrazine(1.1 mmol), K2CO3 (1.5 mmol),and dioxane (2 ml). The reaction mixture was stirredunder a nitrogen atmosphere at 110 Cfor 24 h. The reaction mixture was cooled to room temperature; the reaction mixture was extracted with diethylether (5¡Á3 ml). The combined extracts was washed withbrine and dried over MgSO4, and the crude product was adsorbed ontosilica gel and purified by column chromatography (silica gel, petroleum ether:ethyl acetate 20:1) gave the pure saturated carbonyl compound 4.
With the complex challenges of chemical substances, we look forward to future research findings about 1,5-Diphenylpenta-1,4-dien-3-one
