538-58-9, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 1,5-Diphenylpenta-1,4-dien-3-one, cas is 538-58-9,the chiral-oxygen-ligands compound, it is a common compound, a new synthetic route is introduced below.
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).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 1,5-Diphenylpenta-1,4-dien-3-one, 538-58-9
