Abstract

A [4+2] cycloaddition strategy to assemble phenanthren-9-yldiphenylphosphine oxides is reported. This reaction relies on the strategic use of readily available phenylallenyl phosphine oxides as dienes to participate in [4+2] cycloaddition with arynes. Notably, benzo[b][1,4]oxaphosphinin-4-iums can be controllably synthesized by simply tuning the substituents in the phosphine oxide unit through a [2+2] cycloaddition cascade.

苯基烯基膦氧化物与芳烃的取代基依赖性 [4+2] 或 [2+2] 环加成反应。

报告了一种组装菲-9-基二苯基膦氧化物的 [4+2] 环加成反应策略。该反应依赖于战略性地使用现成的苯基烯基膦氧化物作为二烯来参与芳烃的 [4+2] 环加成反应。值得注意的是，只需通过[2+2]环加成级联反应调整氧化膦单元中的取代基，就能可控地合成苯并[b][1,4]氧膦-4-鎓。
