2-Phenylthiocyclobutyl ketones were produced by the reaction of alkenyl sulfides with α,β-unsaturated ketones in the presence of AlCl3. The oxidation with MCPBA and the treatment with LDA or KH of the cycloadducts afford the corresponding 1-cyclobutenyl ketones in good yields.
在 AlCl3 存在下,烯基硫化物与 α、β-不饱和酮反应生成 2-苯基硫环丁基酮。环加载产物经 MCPBA 氧化和 LDA 或 KH 处理后,可以得到相应的 1-环丁烯酮,收率很高。
