A novel palladium(II) catalysed tandem cyclisation of substituted 2-alkenylphenyl alkynones gives substituted 2-vinyl indenones and 6,5,6-fused tricyclic lactone skeletons (pyrones), in one-pot. Wagner-Meerwein-like rearrangements were observed which occur preferentially to conventional chloride-mediated chloropalladations of enynes.
一种新型的钯(II)催化取代的 2-烯基苯基炔酮的串联环化反应,一锅法得到取代的 2-乙烯基茚酮和 6,5,6-稠合的三环内酯骨架(吡喃酮)。观察到 Wagner-Meerwein 型重排,其优先于传统的烯炔氯化钯介导的氯化反应发生。
