Abstract In view of their potential biological properties, different substituted dibenzo [b,e][1,4] dioxins have been synthesized using Diels-Alder reactions. This required the preparation of furobenzodioxins and further dehydration of the bicyclo-adducts of the cycloaddition.

Furo [3,4-b] 1,4-苯并二恶英的 Diels-Alder 反应：取代二苯并 [b,e][1,4] 二恶英的有效方法

摘要 鉴于其潜在的生物学特性，已使用 Diels-Alder 反应合成了不同的取代二苯并 [b,e][1,4] 二恶英。这需要制备呋喃苯并二恶英并进一步使环加成的双环加合物脱水。
