在本文中,描述了2-和3-取代的苯并[ b ]呋喃的完全区域控制的合成。在中性氧化铝存在下,苯酚与α-溴乙酰苯之间的直接反应生成具有完全区域控制能力的2取代的苯并[ b ]呋喃。当使用碱性盐如碳酸钾时,获得了相应的2-氧代醚。由中性氧化铝促进的这些后面化合物的环化产生相应的3-取代的苯并[ b ]呋喃。使用前一种方法,可以在两个制备步骤中从商业来源获得Moracin M和其他类似物。DFT计算提供了合理的反应路径,以了解2-取代的苯并[ b ]呋喃的形成。

In this paper, a fully regiocontrolled synthesis of either 2- and 3-substituted benzo[b]furans is described. Direct reaction between phenols and α-bromoacetophenones in the presence of neutral alumina yields 2-substitutedbenzo[b]furans with complete regiocontrol. When a basic salt such as potassium carbonate is used, the corresponding 2-oxoether is obtained. Cyclization of these latter compounds promoted
