A common heterocyclic compound, 538-58-9,1,5-Diphenylpenta-1,4-dien-3-one, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route. 538-58-9
General procedure: To a solution of dialkyl phosphite (0.01 mol) in anhydrous tetrahydrofuran (30 mL),maintained under a nitrogen atmosphere, sodium (0.02 g) was added and the mixture was stirred at roomtemperature until complete dissolution of sodium. Diarylideneketone 1 (0.01 mol) was then added and themixture heated under reflux for 4 h. After cooling, the reaction mixture was diluted with water (50 mL)and extracted with CHCl3 (2 ¡Á 25 mL). The organic phase was dried over Na2SO4 and concentrated undervacuum. The obtained residue was chromatographed on a silica gel column using a mixture of Et2O andhexane 9:1 as an eluent.
This compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,538-58-9,1,5-Diphenylpenta-1,4-dien-3-one,its application will become more common.
