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。
