| titleOfInvention | Photochemical reaction synthesis for isoflavones |
| abstract | The invention belongs to the technical field of heterocyclic compounds, and particularly relates to a heterocyclic compound with an unhydrogenated heterocycle, a six-membered cycle, and an oxygen atom used as the only heterocyclic atom for being fused with other cycles. The invention provides a novel method for photochemical reaction synthesis for isoflavones. The process of the novel method comprises the following steps of: adding (substituted) 3-(dimethylamino)-1-(2-hydroxylphenyl) propyl-2-alkene-1-ketone, substituted aromatic hydrocarbon and iodine elementary substance in a solvent; reacting under ultraviolet irradiation; performing reduced pressure distillation to recover the solvent after the reaction; and obtaining the compounds disclosed by the invention, namely, isoflavone pure products, via column chromatography separation and purification. The medicinal isoflavones of ipriflavone, formononetin, isoflavoues aglycone, genistein, puerarin and the like are prepared by applying the method, a new technical route is provided for industrialized production for the medicines aforementioned, and a series of novel isoflavone compounds with potential physiological activity are prepared simultaneously. |
