A combined tandem Friedel-Crafts annulation/Claisen rearrangement strategy was developed for the preparation of tetrasubstituted perylenes. Diallyloxyoctahydroperylene was prepared from commercially available 1,2,3,4-tetrahydronaphth-1,5-diol and oxidized with chloranil to the perylene analogue. Claisen rearrangement followed to the novel 2,8-diallylperylene-3,9-diol, which was acylated in situ to
为制备四取代苝,开发了组合串联 Friedel-Crafts 环化/克莱森重排策略。二烯丙氧基八氢苝由市售的 1,2,3,4-四氢萘-1,5-二醇制备,并用氯苯醌氧化成苝类似物。克莱森重排产生了新的 2,8-二烯丙基苝-3,9-二醇,其原位酰化为相应的二辛酸酯。这些结果表明烯丙氧基苝有效地进行克莱森重排,而部分氢化的类似物在相同条件下产生多种产物。
