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: General procedure: A mixture of 8a (70.3 mg, 0.3 mmol) and 1a (172.2 mg, 0.36 mmol) in DMSO (2.0 mL) was stirred under nitrogen atmosphere for 5 min at room temperature. Then DBU (0.065 mL, 0.45 mmol), followed by DMSO (1 mL), was added and the resulting mixture was heated to 80 C in N2 atmosphere. After the reaction was complete, the mixture was filtered through a thin layer (30 mm) of silica gel (100-200 mesh) and washed with DCM. The filtrate was concentrated under reduced pressure and the residue was purified by flash chromatography (PE/EtOAc=60/1) to afford 11a (72.1 mg, 76%).
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.
