A strategy for the synthesis of quinazolinones via Ru‐catalyzed redox isomerization/acceptorless dehydrogenation was proposed and accomplished. In the presence of a commercially available [(p‐cymene)Cl₂]₂, a range of desirable products were obtained with o‐aminobenzamides and allylic alcohols as starting materials in moderate to high yields. This strategy is attractive due to high atom efficiency, and minimal consumption of chemicals and energy.

钌的自动串联催化：通过氧化还原异构化/无受体脱氢反应，从邻氨基苯甲酰胺和烯丙醇到喹唑啉酮

提出并完成了一种通过Ru催化的氧化还原异构化/无受体脱氢合成喹唑啉酮的策略。在可商购的[（对伞花草烯）Cl ₂ ] ₂的存在下，以邻氨基苯甲酰胺和烯丙醇为起始原料，以中等至高收率获得了一系列理想的产品。由于高原子效率以及最少的化学药品和能源消耗，该策略具有吸引力。
