Palladium-catalyzed arene C–H activation/ketone C–H functionalization reaction: route to spirodihydroindenones

Abstract

A novel palladium and norbornene catalyzed arene C–H activation method to synthesize various spirodihydroindenone derivatives was developed. This method produces spirodihydroindenones employing aryl iodides with 2-(2-bromoethyl)-cyclopentanones via a domino reaction, which simplifies the route of building spiro compounds and expands further applications for functional groups selectivity.
