A simple aluminium(III) chloride‐catalyzed synthesis of tri‐substituted furans from aliphatic aldehydes and 1,3‐dicarbonyl compounds was developed by using N‐bromosuccinimide (NBS) as an oxidant. This method was effective for the synthesis of various furan derivatives. Some of the products were not accessible with the previously reported methods. Mechanically, this reaction involved an auto‐tandem
使用N-溴代琥珀酰亚胺(NBS)作为氧化剂,开发了一种简单的氯化铝(III)催化的脂肪族醛和1,3-二羰基化合物合成三取代呋喃的方法。该方法对于合成各种呋喃衍生物是有效的。使用先前报告的方法无法访问某些产品。从机械上讲,该反应涉及一种基于新报道的酸-酸催化串联反应的自动串联催化,以确保呋喃得以成功合成。
