538-58-9 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.
General procedure: In a general procedure, dibenzylidene acetone (1 mmol), N,N-dimethylbarbituric acid/barbituric acid/thiobarbituric acid(1 mmol) and 4 mL of ethanol:water (1:1) were taken in a 50 mL round-bottomed flask. 10 mol% of tetrabutyl ammonium bromide (TBAB) was added to the mixture, and the contents were stirred. The reaction mixture was refluxed and the progress of the reaction was monitored by TLC using ethyl acetate:petroleum ether (30:70) as eluent for disappearance of active methylene compounds. After completion of the reaction, the reaction mixture was allowed to cool to room temperature and diluted with water (5 mL). The solid obtained was filtered at pump and washed with water:ethanol (2:1). The product was recrystallized with ethanol. The products were characterized by their spectral data.
This compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1,5-Diphenylpenta-1,4-dien-3-one,538-58-9,its application will become more common.
