A novel palladium(0)‐catalyzed dearomatizing [2+2+1] spiroannulation of 1‐bromo‐2‐naphthols with aryl iodides and alkynes was developed for the rapid assembly of spiro[indene‐1,1′‐naphthalen]‐2′‐ones. This three‐component cascade reaction was realized through consecutive Catellani‐type C−H activation, unsymmetrical biaryl coupling, alkyne migratory insertion, and arene dearomatization. The potential
开发了一种新型的钯(0)催化1-溴-2-萘与芳基碘化物和炔烃的[2 + 2 + 1]螺环芳环化反应,用于螺[茚-1,1'-萘] -2的快速组装。 '-那些。这种三组分级联反应是通过连续的Catellani型CH活化,不对称联芳基偶联,炔烃迁移插入和芳烃脱芳烃作用实现的。我们的方法的潜在用途是由炔烃系芳基碘化物和1-溴2-萘酚一步合成的dalesconols A和B的多环骨架说明的。
