Abstract A simple, efficient, and general method has been developed for the synthesis of coumarin derivatives through a one‐pot reaction of aromatic aldehydes, 2,2‐dimethyl‐1,3‐dioxane‐4,6‐dione and 5,5‐dimethyl‐1,3‐cyclohexanedione, in the presence of TEBA under solvent‐free conditions using grinding methods. The mild reaction conditions, simple protocol, high yields, and cleaner reaction make this protocol
摘要 通过芳香醛、2,2-二甲基-1,3-二恶烷-4,6-二酮和5,5-二酮的一锅反应,开发了一种简单、高效、通用的合成香豆素衍生物的方法。二甲基-1,3-环己二酮,在TEBA的存在下,在无溶剂条件下使用研磨方法。温和的反应条件、简单的方案、高产率和更清洁的反应使该方案实用且具有经济吸引力。
