Paragraph 0086; 0106; 0108; 0137; 0139, (2018/10/19)
The invention relates to a 4, 4-disubstituted-4, 5-dihydro-1H-imidazole-5-one and derivatives thereof as well as a synthesis method thereof. The synthesis method adopts the technical scheme that amidine compounds and ketones are converted into imidazolone and derivatives thereof in the absence of catalysts just under the action of alkali by using air or oxygen as an oxidant and pyridine, quinoline, triethylamine, NMP, DMA, DMSO, 1, 4-dioxane, toluene and the like as an organic solvent. The synthesis method overcomes the difficulties of the existing method for synthesizing imidazolone compounds of complicated synthesis steps, multi-step synthesis processes as well as the use of metal catalysts, metal oxidants or peroxides of chemical equivalent; and 4, 4-disubstituted-4, 5-dihydro-1H-imidazole-5-one and the derivatives thereof are suitably used as multifunctional materials, and are important raw materials especially for producing the medicine Avapro for treating high blood pressure.
