Knoevenagel/Michael/Aldol reactions of aromatic aldehydes and β-keto esters/ketones in a sequential manner yielded intermediate cyclohexanones in good yields. The latter, on oxidative aromatization with iodine, afforded functionalized biphenyls with at least one phenolic hydroxyl in moderate to good yields.
芳族醛和β-酮酯/酮的Knoevenagel / Michael / Aldol反应以连续的方式以良好的收率得到中间体环己酮。后者在用碘进行氧化芳构化后,以中等至良好的产率获得了具有至少一个酚羟基的官能化联苯。

An Indion 860 mediated cascade reaction of β-ketoester or 1,3-diketone with alkyl/aryl/heteroaryl aldehydes afforded functionalized cyclohexanones in the open air. The catalyst can be recovered and recycled. Combining this methodology with other reactions in the same pot afforded diversity based novel molecules. Some of the synthesized compounds showed inhibition of PDE4 in vitro.
