| Application | chalcone belongs to flavonoids of phenolic compounds. They form one of the largest group of biologically active natural products. The potential anti-cancer, anti-inflammatory, anti-bacterial, anti-oxidant and anti-parasitic properties of naturally occurring chalcone and its unique chemical structure characteristics have stimulated the synthesis of numerous chalcone derivatives. |
| preparation | chalcone can be prepared by aldol condensation reaction of benzaldehyde and acetophenone catalyzed by sodium hydroxide. It has been found that the reaction can also be carried out in the absence of any solvent and is a solid reaction. The reaction of benzaldehyde derivatives and acetophenone has become a part of Green Chemistry in undergraduate chemistry education. In a study of green chemistry, it was found that chalcones can also be synthesized from the same starting materials in warm water (200-350°C). In addition, chalcone derivatives are synthesized by piperidine-mediated condensation to avoid side reactions such as multiple condensation, polymerization and rearrangement. |
| Use | phenylstyrone is a chalcone compound, which is an important organic synthesis intermediate for the synthesis of a variety of drugs. used in organic synthesis, such as sweeteners. |
| biological activity | Chalcone (benzylideneacrophone, phenyl styryl ketone, benzalacrophone, β-phenylacryophone) is an aromatic ketone, it is the center of many important biological compounds (chalcones) with antibacterial, antitumor and anti-inflammatory activities. |
| production method | a mixture of sodium hydroxide solution and ethanol is cooled, vigorously stirred, and freshly distilled acetophenone and benzaldehyde are added, after stirring at 15-30 ° C. For 2-3H, the reactant was gradually thickened, the frozen solution was allowed to stand, yellow precipitate was precipitated, filtered, washed to neutral, and recrystallized with ethanol to obtain chalcone, with a yield of 84%. |
