The construction of different types of substituted arenes was demonstrated through the photocyclization of 2-(fur-3-yl)ethenylarenes using a 3-furyl group as an isopropenyl equivalent synthon in the photocyclization reaction. The furan portion of the photocyclization intermediate could be fragmented via a base-induced elimination reaction to yield a series of substituted polyaromatics, including naphthalene
通过在光环化反应中使用3-呋喃基作为异丙烯基当量合成子,通过2-(呋喃基-3-基)乙烯基芳烃的光环化,证明了不同类型取代的芳烃的构建。可以通过碱诱导的消除反应使光环化中间体的呋喃部分断裂,以产生一系列取代的聚芳族化合物,包括萘,苯并呋喃,苯并噻吩,菲,菲、,和三亚苯基。使用不同的试剂,该方法使得可以在这些芳烃的特定位置处引入甲基或2-羟乙基作为取代基。
