With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.538-58-9,1,5-Diphenylpenta-1,4-dien-3-one,as a common compound, the synthetic route is as follows.

General procedure: To a solution of DVK 1 (0.2 mmol) and active methylene 2 (0.24 mmol) was addedt-Bu-P2 (10uL, 10 mol%) via a micro syringe at room temperature. The reactionmixture was stirred for 2-24 h as indicated in Table 2. The solvent was then removedin vacuo and the crude product was purified by flash chromatography on silica gel(PE/EA = 15:1-10:1) to give the desired product 3.

As the paragraph descriping shows that 538-58-9 is playing an increasingly important role.

General procedure: To a stirred solution of indole 1a (59 mg, 0.5 mmol) and chalcone 2a (115 mg, 0.55 mmol) in MeCN (2.0mL) was added a solution of Br2 (0.00077 mL) in MeCN (0.5 mL), and the mixture was stirred for 7.0 h at 50 C. After 1a was consumed, as indicated by TLC, the reaction mixture was quenched with saturated aqueous Na2S2O3 (0.2mL) and water (10.0 mL), and extracted with CH2Cl2 three times. The residue obtained after evaporation of the solvent was purified by column chromatography on silica gel (petroleum ether-ethyl acetate = 30:1, v/v) to afford adduct 3a as a white solid (151 mg, 93% yield).

Step 1. Under a nitrogen atmosphere, add 8 L of absolute ethanol and 0.112 kg of anhydrous sodium acetate to a glass reactor heated in a water bath.When the system temperature was heated to 68 C, 0.92 kg of dibenzylideneacetone obtained in Example 1 was added.After stirring for 30 minutes, add ice to the water bath heater to quickly cool the system down to 60 C.Then, 0.2 kg of palladium dichloride prepared in Example 1 was added and reacted at 60 C for 2 hours.Funnel filtration gave bis (dibenzylideneacetone) palladium (0);
