preparation example Construction

[0049] In the preparation method of the present invention, the reaction temperature is 0-30°C, non-limitingly, for example, it can be 0°C, 10°C, 20°C or 30°C

[0050] (6) Response time

[0051] In the preparation method of the present invention, the reaction time is not particularly limited. For example, the appropriate reaction time can be determined by detecting the residual percentage of the target product or raw material through liquid chromatography, which is usually 1-3 hours, non-limitingly for example 1 hour, 2 hours and 3 hours.

[0052] (7) Separation and purification

[0053] The mixture obtained after the reaction can be further separated and purified to obtain a purer final product. Those of ordinary skill in the art are well-known methods for separation and purification, for example, methods such as extraction, column chromatography, distillation, decantation, filtration, centrifugation, washing, evaporation, stripping and adsorption or a combination of at leas...

Abstract

The invention belongs to the technical field of organic compound synthesis and particularly relates to a preparation method of an alpha, beta-diphenyl-1-aryl-acrylketone compound. According to the preparation method, in an organic solvent, diphenylcyclopropenone with structure as shown in a formula (I) and arylboronic acid with structure as shown in a formula (II) are taken as reaction materials, and the alpha, beta-diphenyl-1-aryl-acrylketone compound with structure as shown in a formula (III) is obtained through ring-opening reaction of cycolpropenone in the presence of a palladium catalyst; and in the formula (II) and the formula (III), R is independently selected from one of H, methyl, chlorine, trifluoromethyl, phenoxy, vinyl, fluorine, a formyl group, isopropyl, n-propyl, cyan, tertiary butyl, nitro or phenyl.

Description

technical field [0001] The invention belongs to the technical field of organic compound synthesis, and in particular relates to a preparation method of α,β-diphenyl-1-arylpropenone compound. Background technique [0002] Chalcone is an active substance that widely exists in plants in nature. Due to its greater flexibility and ability to bind to different receptors, it exhibits a broad spectrum of biological activities, such as anti-tumor, anti-virus, anti-bacterial, anti-inflammatory Wait. In addition, the α,β-enone structure has electrophilic activity, and is more inclined to interact with soft nucleophiles such as thiol compounds in the body, rather than interacting with hard nucleophiles such as amino groups and hydroxyl groups in nucleic acids, so as to avoid mutations or nucleophiles. Cancer, therefore, the safety of this type of structural compounds is relatively high. Therefore, it is of great significance to use chalcone as the lead compound for structural modifica...
