2-arylbenzofuran in good yield, and a mechanism for this chemical conversion involving loss of one carbon unit was described. This reaction scheme was suggested as a plausible chemical analogy for the corresponding biosynthetic process of 2-arylbenzofuran of isoflavonoid origin, and a new biosynthetic scheme depicting 2-hydroxy-isoflav-3-ene as the possible common intermediate for both 2-arylbenzofuran and
用酸处理2-羟基-异黄酮-3-烯可得到高产率的2-芳基苯并呋喃,并且描述了这种化学转化的机理,该机理涉及一个碳单元的损失。该反应方案被认为是异黄酮来源的2-芳基苯并呋喃的相应生物合成过程的合理的化学类比,并且新的生物合成方案描述了2-羟基-异黄酮-3-烯为2-芳基苯并呋喃和3的可能的常见中间体。提出了-芳基香豆素。通过使用该化学方案,还可以合成有效的抗菌剂2-芳基苯并呋喃植物抗毒素,维格呋喃。
