A strategy for the synthesis of the furan-fused tetracyclic core of halenaquinol and halenaquinone was explored through a model study. The synthesis involved the intramolecular [4+2] cycloaddition reaction of the o-quinodimethane, generated from benzocyclobutene as the key step.
通过模型研究探索了合成呋喃并稠合的对苯二酚和对苯二酚的四环核心的策略。合成涉及邻苯二环丁烯生成的邻喹啉甲烷的分子内[4 + 2]环加成反应,这是关键步骤。
