An unusual (4+1), instead of a normal (4+2), cycloaddition has been developed between benzocyclobutenones and styrene-type alkenes via the Rh-catalyzed C−C activation, which provides a distinct one-carbon ring expansion approach to access multi-substituted 2-indanones.
通过 Rh 催化的 C−C 活化,苯并环丁烯酮和苯乙烯型烯烃之间形成了一种不寻常的 (4+1) 环加成反应,而不是正常的 (4+2) 环加成反应,这提供了一种独特的单碳环扩展方法获得多取代的2-茚满酮。
