Paragraph 0024-0026, (2021/06/26)
The invention discloses an isatin-1,2,4-diazole compound and a preparation method and application thereof. The structural general formula of the isatin-1,2,4-diazole compound is shown in the specification. According to the splicing principle of drugs and the structural drug molecular design concept, a five-membered heterocyclic structure is introduced to an isatin molecular skeleton of isatin, and the isatin-1,2,4-diazole derivative is obtained. A biological activity test result shows that the isatin-1,2,4-diazole compound disclosed by the invention has good inhibitory activity on mouse mononuclear macrophage leukemia cells.

We present here two new methods based on rearrangement reactions to obtain novel 2-substituted 3-hydroxy-4-oxo-1,4-dihydroquinolines, an important family of heterocycles with potential applications. Alkyl 3-hydroxy-4-oxo-1,4-dihydroquinoline-2-carboxylates were obtained by alkoxide promoted rearrangement of alkyl isatinacetates. A second synthetic route involves the alkoxide promoted reaction of both isatin and N-methylisatin, with alkylating agents having acidic methylenes. This reaction leads to the formation of spiroepoxyoxindoles via Darzens' condensation. When phenacyl bromides are used, the initially obtained benzoyl substituted spiroepoxyoxindoles were smoothly transformed into the corresponding 2-benzoyl-3-hydroxy-4-quinolinones with good to excellent yields.
