Controlling the reaction temperature at 50 °C, 80 °C, and 110 °C, respectively, the iodine-catalyzed reaction of 2-aminobenzamides with 1,3-cyclohexanediones gave structurally diversified products. In the latter, it gave bis-quinazolin-4(3H)-ones unexpectedly, with 1,3-cyclohexanediones ring-opening.
将反应温度分别控制在50°C,80°C和110°C,碘催化的2-氨基苯甲酰胺与1,3-环己二酮的反应可得到结构多样化的产物。在后者中,它意外地给出了带有1,3-环己二酮开环的双喹唑啉-4(3 H)-。
